Bits 7 to 0: Transmit DS0 Channel Bits (B[1:8]). Transmit channel data that has been selected by the
TDS0SEL
register. B8 is the LSB of the DS0 channel (last bit to be transmitted).

Bits 7 to 0: Transmit Blank Channel Select for Channels 1 to 32 (CH[1:32])
0 = Transmit TSERn data from this channel.
1 = Ignore TSERn data from this channel.
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) then the RSZS bit can be
set to one, which may provide a lower occurrence of slips in certain applications.
