3.10.6.1 Illegal Code Remapping
If the ILLEGAL_REMAP bit of the IOPROC_DISABLE register is set LOW, the
GS1560A will remap all codes within the active picture between the values of 3FCh
and 3FFh to 3FBh. All codes within the active picture area between the values of
000h and 003h will be re-mapped to 004h.
In addition, 8-bit TRS and ancillary data preambles will be remapped to 10-bit
values if this feature is enabled.
3.10.6.2 EDH CRC Error Correction
The GS1560A/GS1561 will generate and insert active picture and full field CRC
words into the EDH data packets received by the device. This feature is only
available in SD mode and is enabled by setting the EDH_CRC_INS bit of the
IOPROC_DISABLE register LOW.
EDH CRC calculation ranges are described in
EDH CRC Error Detection on
page 58
.
NOTE: Although the GS1560A/GS1561 will modify and insert EDH CRC words
and EDH packet checksums, EDH error flags will not be updated by the device.
