CRC_ENABLE CRC CGMS-A Sequence, Address 0xB2[2]
For certain video sources, the CRC data bits can have an invalid
format. In such circumstances, the CRC checksum validation
procedure can be disabled. The CGMSD bit goes high if the
rising edge of the start bit is detected within a time window.
Rev. B | Page 49 of 104
When CRC_ENABLE is 0, no CRC check is performed.
The CGMSD bit goes high if the rising edge of the start bit
is detected within a time window.
When CRC_ENABLE is 1 (default), CRC checksum is used to
validate the CGMS sequence. The CGMSD bit goes high for a
valid checksum. ADI recommended setting.

Figure 31 shows the bit correspondence between the analog
video waveform and the WSS1/WSS2 registers. WSS2[7:6]
are undetermined and should be masked out by software.

Figure 32 shows the bit correspondence between the analog
video waveform and the EDTV1/EDTV2/EDTV3 registers.
EDTV3[7:6] are undetermined and should be masked out by
software. EDTV3[5] is reserved for future use and, for now,
contains a 0. The three LSBs of the EDTV waveform are
currently not supported.
