Notes
1. This current is the maximum allowed into the inputs when line and field flyback signals are connected to these inputs.
Series current limiting resistors must be used to limit the input currents to ±1 mA.
2. RGBREF is the positive supply pin for the RGB output pins and it must be able to source the IOH current from the
R, G and B pins. The leakage specification on RGBREF only applies when there is no current load on the RGB pins.

IVT1.1BMCX page memory organization

The organization of the page memory is illustrated by Fig.11. The IVT1.1BMCX provides an additional row as compared
with first generation decoders; this brings the display format up to 40 characters by 25 rows. Rows 0 to 23 form the
teletext page; Row 24 is the extra row available for software generated status messages and FLOF/FASTEXT prompt
information.

Notes
1. The dash (−) indicates these bits are inactive and must be written to logic 0 for future compatibility.
2. All bits in registers R0 to R10 are cleared to logic 0 on power-up except bits D0 and D1 of Registers R1, R5 and R6
which are set to logic 1.
3. All memory is cleared to space (00100000) on power-up, except Row 0 Column 7 Chapter 0, which is alpha white
(00000111) as the acquisition circuit is enabled but the page is on hold.
4. TB must be set to logic 0 for normal operation.
5. The I2C-bus slave address is 0010001.

Table 8 Register description

R0 ADVANCED CONTROL - auto increments to register 1

R11/R11B SELECT selects reading of R11 or R11B
DISABLE ODD/EVEN forces ODD/EVEN output LOW when logic 1
DISPLAY STATUS ROW when SET = 1 and R1D6 = 1 open (8-bit mode) then all the text display is blanked
out apart from the status row, this allows the page memory to be used for
non-textural data, such as in the German TOP system
DISABLE HDR ROLL disables green rolling header and time
AUTO ODD/EVEN when set forces ODD/EVEN LOW if any TV picture displayed, if DISABLE
ODD/EVEN = 0
FREE RUN PLL will force the PLL to free run in all conditions
X24 POS automatic display of FASTEXT prompt row when logic 1
R1 MODE - auto increments to register 2
T0, T1 interlace/non-interlace 312/313 line control (see Table 10)
TCS ON text composite sync or direct sync select (see Table 10 for FFB mode selection)
DEW/FULL FIELD field-flyback or full-channel mode
DISABLE PKT 26 disable automatic processing of packet 26
ACQ ON/OFF acquisition circuits turned off when logic 1
7 + P/8-BIT 7-bits with parity checking or 8-bit mode
VCS TO SCS when logic 1 enables display of messages with 60 Hz input signal
R2 PAGE REQUEST ADDRESS - auto increments to register 3
COL SCO - SC2 point to start column for page request data (see Table 9)
TB must be logic 0 for normal operation
R3 PAGE REQUEST DATA - does not auto increment (see Table 9)

CLOCK SYSTEMS
Crystal oscillator
The crystal is a conventional 2-pin design operating at 27 MHz. It is capable of oscillating with both fundamental and third
overtone mode crystals. External components should be used to suppress the fundamental output of the third overtone
as illustrated in Fig.13.

CHARACTER SETS
The WST specification allows the selection of national character sets via the page header transmission bits, C12 to C14.
The basic 96 character sets differ only in 13 national option characters as indicated in the Tables 16, 17 and 18 with
reference to their table position in the basic character matrix illustrated in Table 15. The IVT1.1BMCX automatically
decodes transmission bits C12 to C14. Tables 12, 13 and 14 illustrate the character matrixes.
Character bytes are listed as transmitted from b1 to b7.

1. These control characters are reserved for compatibility with other data codes.
2. These control characters are presumed before each row begins.
3. Control characters shown in Columns 0 and 1 are normally displayed as spaces.
4. Characters may be referred to by column and row (for example 2/5 refers to %).
5. Black represents displayed colour. White represents background.
6. The SAA5249 national option characters are illustrated in Tables 16, 17,18 and 19.
7. Characters 8/6, 8/7, 9/5, 9/6 and 9/7 are special characters for combining with character 8/5
(E, H and T codes only).
8. National option characters will be displayed according to the setting of control bits C12 to C14. These will be mapped
into the basic code table into positions shown in Tables 16, 17, 18 and 19.
9. Columns 2a, 3a, 6a and 7a are displayed in graphics mode.
