4. INTERFACE TYPES AND OPERATIONAL MODES

This section describes two interface type and three operational modes of HC08-Programmer.
In-Circuit Programming and On-Board Programming interfaces are available in HC08Programmer. MON08, Security Sequence Auto Search and Enter Security Sequence modes are
available.

ETL 2002-2005 MC68HC908AZ60 Programmer Serial Port Version Users Guide

4.1 IN-CIRCUIT PROGRAMMING

Generally, In-Circuit programming interface useful for fast access to target MCU EEPROM
resources. In this mode HC08-Programmer automatically detects target MCU bus speed. Ceramic
resonator connected to target MCU must be in range from 1.6 MHz to 16 MHz. Also pins PTC0,
PTC1, PTC3 must be correct configured to achieve required MCU bus speed (see Appendix
Figure3). If the ceramic resonator frequency low than 1.6 MHz, use clock overriding from HC08Programmer. On the CNT2 connector, OSC1 pin support external 8MHz clock frequency to target
MCU. Connect this pin to target MCU OSC1 pin. For circuit stability any components on MCU
OSC1, OSC2 pins such as capacitors, resistors and crystal resonator must be disconnected.

&
&

Note: Devices MC68HC908AZ60 (4J74Y), MC68HC08AZ60 (1J35D) has

modified monitor ROM: On-board programming available only!
Note: Device MC68HC08AZ32A (1L52H) has extended security possibilities,
so knowledge of Security Sequence required.

4.2 ON-BOARD PROGRAMMING

On board programming interface type is basic for HC08-Programmer. In this interface type all
programmer features are available. For example, FLASH reading, programming possible only with
this interface type. Target MCU must be mounted to the corresponding adaptor QFP64, QFP100 or
PLCC52 supplied with HC08-Programmer. Regarding of operation mode external 800 KHz or
8MHz frequency supplied to MCU. Also, for Security Sequence passing specific power control
realized.

&

Note: When target adaptor with MCU mounted check contacts careful to avoid
short circuit. Otherwise HC08-Programmer voltage regulator can be damaged!

4.3 MON08 MODE

This mode uses standard Motorola 08 Family MCU interface (see Appendix Figure 3). To
enter this mode, defined conditions must be established. High voltage (10V) on IRQ pin, High
level on PTC0 pin and Low levels on PTC1, PTC3. The PTA0 pin use for communication with
host PC. Because of slow speed communication via PTA0 pin, HC08-Programmer realizes
EEPROM reading, programming only. If In-Circuit programming interface selected, before
passing Security Sequence HC08-Programmer automatically detects target MCU communication
speed. After speed founded, standard MON08 protocol is performed. If On-Board programming
interface selected, communication speed fixed according device type, and MON08 protocol is
performed immediately. Also if MCU dont have additional SCI interface pins (TxD, RxD) or
these pins are damaged, MON08 mode is only one way to establish connection with MCU.

4.4 AUTO SS MODE

This mode is main difference from other programmers for 08 Motorola family devices. In this
mode HC08-Programmer automatically search the Security Sequence and passing it. Than, if
required, Security Sequence automatically stored in SSList.txt file. New, found SS than can be
used in future in Enter SS mode (see Section 4.5). This mode is useful for reading FLASH contents
of MCU. Also on some devices such as MC68HC08AZ32A (1L52H) even EEPROM contents
couldnt be read without knowledge of Security Sequence.

ETL 2002-2005 MC68HC908AZ60 Programmer Serial Port Version Users Guide

Because of using additional SCI interface pins (TxD, RxD) reading, writing of MCU
performed on high speed.

&
&

Note: Security Sequence Auto search based on analyzing of electrical current

noise on Motorola device power pins. So any equipment with high level of
electromagnetic radiation must be switched off.
Note: Auto SS mode implemented for educational purposes only.

4.5 ENTER SS MODE

This mode implemented for full working with all FLASH, ROM, EEPROM areas of MCU.
Only entering of right Security Sequence will allow user full access to MCU resources. Security
Sequence located from $FFF6 to $FFFD address in memory space of MCU. Every time when host
PC trying to establish connection with MCU correct Security Sequence must be entered. For work
facilitation with Security Sequences HC08-Programmer automatically analyze all operations with
$FFF6-$FFFD areas and if required, store new Security Sequence in SSList.txt file. This file can
be found in the same directory as HC08-Programmer software. To load SS from file press
LoadSS button, select required Security Sequence and press OK button. Also, User can see is
MCU secured or unsecured in HC08-Programmer log window.
Because of using additional SCI interface pins (TxD, RxD) reading, writing of MCU
performed on high speed.

Program memory of these devices formed while manufacturing of MCU by Motorola. So any
attempts to reprogram ROM section will be failed. Only EEPROM reading, programming
operation is available for this type of devices. Working with EEPROM area not differs from work
with customary devices (see Section 5.1).

5.3 MC68HC908AZ60 4J74Y MASKSET

This section describes the algorithm to work with MC68HC908AZ60 device, 4J74Y maskset.
The device has non standard security scheme. As against to 08 family devices, security byte
placed in EEPROM1 area in address $0800. If value of this byte equal $D3, the device
permanently secured, without possibilities to unlocking. To break through this security only OnBoard programming interface and Auto SS mode can be used. After HC08-Programmer
successfully finish unlocking procedure value of security EEPROM cell can be changed to $FF.
After next power on reset device became unsecured.

6. EEPROM STRUCTURE
All Motorola devices 08 family has same EEPROM structure shortly described below.

6.1 EEPROM BLOCK 1

EEPROM1 - 512 bytes located from $0800 to $09FF.
EENVR1 - Nonvolatile Register (Block Protect Options and EEPROM1, 2 Security)*
EE1DIVH - Nonvolatile Divider Register High* (Not present on some devices see Table 5)
EE1DIVL - Nonvolatile Divider Register Low* (Not present on some devices see Table 5)
Extra care must be taken when programming EEPRTCT bit (4 bit) in EENVR1.
Once the EEPRTCT bit is programmed to 0 for the first time:
Programming and erasing of secured locations $08F0 to $08FF is permanently disabled.
Programming and erasing of EE1NVR is permanently disabled.
Bulk and Block Erase operations are disabled for the unprotected locations $0800-$08EF,
$0900-$09FF.
Extra care must be taken when programming EEDIVSECD bit (7 bit) in EE1DIVH.
Once EEDIVSECD in the EE1DIVH is programmed to 0 and after a system reset, the E1DIV
security feature is permanently enabled because the EEDIVSECD bit in the EE1DIVH is
always loaded with 0 thereafter. Once this security feature is armed, erase and program
moderate disabled for EE1DIVH and EE1DIVL. Modifications to the EE1DIVH and
EE1DIVL registers are also disabled.

6.2 EEPROM BLOCK 2

This EEPROM area not present on some devices (see Table 5).
EEPROM2 - 512 bytes located from $0600 to $07FF.
EENVR2 - Nonvolatile Register (Block Protect Options and EEPROM1, 2 Security)*
EE2DIVH - Nonvolatile Divider Register High* (Not present on some devices see Table 5)
EE2DIVL - Nonvolatile Divider Register Low* (Not present on some devices see Table 5)
Extra care must be taken when programming EEPRTCT bit (4 bit) in EENVR2.
Once the EEPRTCT bit is programmed to 0 for the first time:
Programming and erasing of secured locations $06F0 to $06FF is permanently disabled.
Programming and erasing of EE2NVR is permanently disabled.
Bulk and Block Erase operations are disabled for the unprotected locations $0600-$06EF,
$0700-$07FF.
Extra care must be taken when programming EEDIVSECD bit (7 bit) in EE2DIVH.
Once EEDIVSECD in the EE2DIVH is programmed to 0 and after a system reset, the E1DIV
security feature is permanently enabled because the EEDIVSECD bit in the EE2DIVH is
always loaded with 0 thereafter. Once this security feature is armed, erase and program
moderate disabled for EE2DIVH and EE2DIVL. Modifications to the EE2DIVH and
EE2DIVL registers are also disabled.

8. FILE OPERATIONS
This section describes basic rules of working with files. Memory dump from Hex Editor
(Buffer) can be load/save from/to hard disk. Also short descriptions such as project name, MCU
type and memory cell assignment can be done for future fast remind. HC08-Programmer accepts
tree types of file formats:
9 BIN (Binary format)
9 S-Record (Motorola S19, S20 Records format)
9 EEF (Extended ETL Format)

8.1 LOAD FILE INTO BUFFER

Select File>Open menu item.

Press Browse button.
In File Open Dialog window, select file witch need to be open.
Press Open button.
Than opposite Auto Format Detected: text, select correct file format. Note that software
try automatically detects file format, but unknown records in file will fail this detection.
Load Entire file check box must be checked if automatically loading procedures
required.
Than press OK button.
Sometimes load data from file to specific buffer allocations required. For Example if required
load buffer from $0400 address from binary file beginning from $0000 address follow next steps:
Select File>Open menu item.
Press Browse button.
In File Open Dialog window, select file which need to be open.
Press Open button.
Than, opposite Auto Format Detected: select Binary format.
Uncheck Load Entire File check box.
In field Offset Value to Place Data to Buffer: enter 0x0400.
Than press OK button.
Now data placed to Hex Editor Buffer from the beginning of 0x0400 address.
If more complicated operations with files required, for example load Hex Editor Buffer from
many files Lowest Address From File To Load, Highest Address From File To Load and
Clear Buffer Before Loading File options are available.

8.2 SAVE FILE FROM BUFFER

Select File>Save menu item.

Press Browse button.
Select directory in which file will be saved.
Type file name, for example test1
Press Save button.
Than select format in which file will be saved*.
Press OK button.

&

Note: Use EEF Format for future Load File Into Buffer automatically
processing. Also, only in EEF Format Project Description, Device Name and
Memory Cells attributes can be saved.

9. ERRORS AND TROUBLESHOOTING

This section describes most recently encountered problems, errors and fixing solutions.
Problem: LED1 (see Figure 1) Dark.
Causes: This problem can accrue when external power supply connected to HC08Programmer broken or connected in wrong polarity.
Solutions: Check voltage on HC08-Programmer power clamps. It must be 12 V +/- 1V.
Problem: LED1 (see Figure 1) Red.
Causes: This problem can accrue when external power supply voltage or voltage on IRQ
pin (2 pin Motorola device socket) lower than 9.5 Volt.
Solutions: Remove any adaptors from Motorola device socket. Check voltage on HC08Programmer power clamps. It must be 12 V +/- 1V.
Problem: LED3 on HC08-Programmer still Green when LED1 became Orange.
Causes: This problem can accrue when logical levels on PTC0, PTC1, PTC3 pins not
correspond to MON08 monitor requirements or if Built-in Voltage Regulator
damaged.
Solutions: Disconnect PTC0, PTC1, PTC3 pins from target board. If LED3 appears Orange
on attempting to Link Device, connect pin by pin to MCU to find out which pin
need to be released from external components. If after relishing PTC0, PTC1,
PTC3 pins LED3 not Orange, possible Voltage Regulator is broken.
Error Message: "Reset line must be in 'High' state"
Causes:
This message can appear when MCU Reset pin connected to ground thru
external components or no oscillation on OSC1, OSC2 pins.
Solutions:
Check MCU reset pin resistance relatively to VSS pin, and if it too low
checks passive, active components connected. Or check integrity of ceramic
resonator and passive components connected to OSC1, OSC2 pins.
Error Message: "PTA0 line must be in 'High' state"
Causes:
This message can appear when MCU PTA0 pin connected to ground thru
external components.
Solutions:
Cut any component from pin.
Error Message: "No Echo from MCU"
Causes:
This message can appear when target MCU not connected; logical levels on
PTC0, PTC1, PTC3 pins and voltage on IRQ pin not correspond to MON08
monitor requirements.
Solutions:
Check MON08 monitor requirements according Appendix Figure 3.
Error Message: Wrong Echo from MCU"
Causes:
This message can appear when wrong Device selected. Communication
speed not corresponds to this device.
Solutions:
Select correct device type; take attention on MCU maskset.
Error Message: "IRQ line must be in 'High' state"
Causes:
This message can appear when MCU IRQ pin connected to ground thru
external components.
Solutions:
Cut any component from IRQ pin.

 Error Message: "Communication Error"

Causes:
This message can appear when Communication between HC08-Programmer
and PC broken.
Solutions:
Try to decrease baud rate in Tools>Ports Options dialog window. Also
this message can appear when COM port cable has poor contact with DB-9
connectors.
Error Message: "Monitor firmware Check Sum Error"
Causes:
This message can appear after monitor firmware loaded into target MCU
with errors.
Solutions:
Try to reconnect to target MCU. If this error not disappeared, possible target
MCU has damaged RAM.
Error Message: "NO response from MCU, possible RAM, RxD or TxD pins damaged"
Causes:
This message can appear after monitor firmware loaded into target MCU
and waiting for echo time out error encored. Also additional pins (RxD,
TxD) used for On-Board programming disconnected or damaged.
Solutions:
Trace contact form RxD, TxD pins to pins on adaptor. Try to reconnect with
target MCU. If this error not disappeared, possible target MCU has damaged
RAM.
Error Message: "NO response from MCU, possible RAM damaged"
Causes:
This message appeared at the same conditions as described above with the
exception of only PTA0 pin used for echo reply.
Solutions:
Trace contact form PTA0 pin to pins on adaptor. Try to reconnect to target
MCU. If this error not disappeared, possible target MCU has damaged
RAM.
