very briefly mentioned on page 6 of the DDC-03282 data sheet.
SDEN1,2 X1,2 Y1,2 S/D code check enable and check bits. If SDENx is set to 1 then
the corresponding receiver checks for the X and Y bits to match. If set to 0 then all
properly formatted data is received.
PARCK Parity Check Enable A 1 causes even parity and a 0 selects odd parity for the
transmitter if PAREN is set.
TXSEL, RCVSEL 0 = 100K transmit or receive speed and 1 selects 12.5K. Transmitter
needs to match the receiver of the data stream not necessarily the receiver within the
same device. Both receiver channels are affected by the selection within the same
channel.
WLSEL Word length select. 0 = 32 bits, 1 = 25 bits in length.
In general, the control word options should only be changed when the device is placed
in the reset state with control register 1.
