Bits 7 to 0: Transmit Blank Channel Select for Channels 1 to 32 (CH[1:32]).
Note that when two or more sequential channels are chosen to be ignored, the receive slip zone select bit should
be set to zero. If the ignore channels are distributed (such as 1, 5, 9, 13, 17, 21, 25, 29), the RSZS bit can be set to
one, which may provide a lower occurrence of slips in certain applications.
0 = transmit TSER data from this channel
1 = ignore TSER data from this channel
