Bits 7 to 0: Receive Blank Channel Select for Channels 1 to 32 (CH[1:32])
Note that when two or more sequential channels are chosen to be blanked, the receive-slip zone select bit should
be set to zero. If the blank 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.
0 = Do not blank this channel (channel data is available on RSERn).
1 = Data on RSERn is forced to all ones for this channel.
