Disables insertion of ancillary data
checksums for 3G Level B Data
Stream 1, 3G Level A, HD and SD
inputs.
Disables insertion of HD/3G CRC
words for 3G Level B Data Stream
1, 3G Level A, and HD inputs.
Disables insertion of line numbers
for 3G Level B Data Stream 1, 3G
Level A, and HD inputs.
Disables insertion of TRS words for
3G Level B Data Stream 1, 3G Level
A, HD and SD inputs.
Reserved.
Disables 8-bit TRS word remapping
in Data Stream 2 (3G Level B only).
Reserved.
Disables regeneration of the
SMPTE 352M packet for 3G Level B
data. Note: this bit needs to be
enabled via the host interface to
disable SMPTE 352M packet
generation. It is strongly
recommended to set this bit LOW
only when Level B to Level A
conversion is enabled.
Swaps Data Stream 1 (DS1) and
Data Stream 2 (DS2) at the output
in 3G mode.
In 20-bit output mode, DS1 shall be
present on DOUT pins [19:10] and
DS2 shall be present on DOUT pins
[9:0] by default. When
DS_SWAP_3G is set to '1', DS2 shall
be present on DOUT pins [19:10]
and DS1 shall be present on DOUT
pins [9:0]
In 10-bit (DDR) output mode, DS2
shall precede DS1 by default. When
DS_SWAP_3G is set to '1', DS1 shall
precede DS2.
Disable conversion of a 3G Level B
input to a 3G Level A format. Only
effective if in 3G Level B mode.
Default is active HIGH (disabled), so
Level B inputs are formatted as
Level B outputs.
