PINNING 1 Vpo Power supply: + 5 V power supply pin. 2,3,40 A11, A12, A10 Chapter Address: three outputs that select which 1 K byte chapter of external RAM is being accessed for any read or write cycle.
4 OE Output Enable: active low output signal used to control the
reading of the external RAM. It occurs continuously at a 1 MHz rate.

Enhanced computer controlled teletext circuits SAA5243 SERIES
5 WE Write Enable: active low output signal used to control the writing
of data to the external RAM. It.occurs for a valid write cycle only and is interleaved with the read cycles.
6 TTD Teletext Data: input from the SAA5231 Video Input Processor
(VIP2). It is clamped to Vgg for 4 to 8 us of each television line to maintain the correct DC level following the external AC coupling. 7 TTC Teletext Clock: 6.9375 MHz clock input from the SAA5231. It is internally AC coupled to an active clamp input buffer.
8 ODD/EVEN Odd/Even: for interlaced mode, the output changes once per field at
2 us before the end of line 311 (624). The output is high for even fields and low for odd fields.
9 F6 Character display clock: 6 MHz clock input from the
SAA5231. It is internally AC coupled to an active clamp input buffer. 10 vcs Video Composite Sync: input from the SAA5231 derived from the incoming video signal. Sync pulses are active high.
11 SAND Sandcastle: 3-level sandcastle output to the SAA5231 containing
the phase locking and colour burst blanking information.
12 TCS/SCS Text Composite Sync/Scan Composite Sync: as an output an
active low composite sync waveform (TCS) with interlaced or non-interlaced format (see Fig.6) which is fed to the SAA5231 to drive the display timebases. Alternatively this pin can act as an input for an active low composite sync waveform (SCS) to ‘slave’ the display timing circuits. 13, 14,15 R,G,B Red, Green, Blue: these 3 open drain outputs are the character video signals to the television display circuits. They are active high and contain character and background information.
16 COR Contrast Reduction: open drain, active low output which allows
selective contrast reduction of the television picture to enhance a mixed mode display.
17 BLAN Blanking: open drain, active high output which controls the
blanking of the television picture for a normal text display and for a mixed display.
18 Y Character foreground: open drain, active high video output signal
containing all the foreground information displayed on the television screen (e.g. for driving a display printer). 19 SCL Serial Clock: input signal which is the |?C-bus clock from the microcontroller. 20 SDA Serial Data: is the |?C-bus data line. It is an input/output function with an open drain output. 21 Vss Ground: 0 volts. 22-29 DO-D7 8 RAM data lines: 3-state input/output pins which carry the data bytes to and from the external RAM. 30-39 A0-A9 RAM address: 10 output signals that determine which byte location within a 1 K byte chapter of external RAM is accessed for any read or write cycle.

Enhanced computer controlled teletext circuits SAA5243 SERIES RowO Row 0 is for the page header. The first seven columns (0 to 6) are free for status messages. The eighth is an alphanumeric white or green control character, written automatically by ECCT to give a green i rolling header when a page is being looked for. The last eight characters are for rolling time. | Row 25 if The first 10 bytes of row 25 contain control data relating to the received page. Seven digits are used to identify a page as shown in Table 1. The remaining 14 bytes are free for use by the microcomputer. Register maps . ECCT mode registers R1 to R11 are shown in Table 2. R1 to R10 are WRITE only; R11 is READ/WRITE. Register map (R3), for page requests, is shown in detail in Table 3. Table 2 ECCT register map a ee ee ee TA 7¥P/ | aca. EXTENSION] DEW? | TCs 1 TO

Abbreviations are as for Table 1 except for DO CARE bits. When the DO CARE bitis set to logic 1 this means the corresponding digit is to be taken into account for page requests. If the DO CARE bit is set to logic O the digit is ignored. This allows, for example, ‘normal’ or ‘timed page’ selection. If HOLD is set LOW, the page is held and not updated. There are four groups of data shown in Table 3, one for each acquisition circuit (four simultaneous page requests). Columns auto-increment on successive |?C transmission bytes. March 1991 601
SAA5243 SERIES . APPLICATION INFORMATION (continued) CHARACTER SETS Several versions of the ECCT are available, offering a variety of character sets. The full character sets | are shown in Tables 4a to 4d. The world system teletext specification allows the selection of national character sets via the page header transmission bits, C12 to C14. These bits are automatically decoded by the ECCT, the resulting character sets are shown in Tables 6a to 6d.
