TELETEXT CONTROL REGISTER TC07 (TC07–TC00)
(ADDRESS (SR4–SR0) = 1CH)
Teletext Control Register is an 8-bit-wide register. See Figure
59.
TTXREQ Rising Edge Control (TC07–TC04)
These bits control the position of the rising edge of TTXREQ.
It can be programmed from zero CLOCK cycles to a max of 15
CLOCK cycles.
TTXREQ Falling Edge Control (TC03–TC00)
These bits control the position of the falling edge of TTXREQ.
It can be programmed from zero CLOCK cycles to a max of 15
CLOCK cycles. This controls the active window for Teletext
data. Increasing this value reduces the amount of Teletext Bits
below the default of 360. If Bits TC03–TC00 are 00Hex when
Bits TC07–TC04 are changed, then the falling edge of TTREQ
will track that of the rising edge (i.e., the time between the
falling and rising edge remains constant).
CGMS_WSS REGISTER 0 C/W0 (C/W07–C/W00)
(ADDRESS (SR4–SR0) = 19H)
CGMS_WSS Register 0 is an 8-bit-wide register. Figure 60
shows the operations under control of this register.

C/W BIT DESCRIPTION
CGMS Data Bits (C/W03–C/W00)
These four data bits are the final four bits of CGMS data output
stream. Note it is CGMS data ONLY in these bit positions i.e.,
WSS data does not share this location.
CGMS CRC Check Control (C/W04)
When this bit is enabled (“1”), the last six bits of the CGMS
data, i.e., the CRC check sequence, are calculated internally by
the ADV7172/ADV7173. If this bit is disabled (“0”), the CRC
values in the register are output to the CGMS data stream.
CGMS Odd Field Control (C/W05)
When this bit is set (“1”), CGMS is enabled for odd fields.
Note that this is only valid in NTSC mode.
CGMS Even Field Control (C/W06)
When this bit is set (“1”), CGMS is enabled for even fields.
Note that this is only valid in NTSC mode.
WSS Control (C/W07)
When this bit is set (“1”), wide screen signalling is enabled.
Note that this is only valid in PAL mode.
