This register provides the channel number used to access the transmit channel
provision RAM. Writing to this register triggers an indirect channel register
access.
CHAN[7:0]:
The indirect channel number bits (CHAN[7:0]) indicate the channel to be
configured or interrogated in the indirect access.
CRWB:
The channel indirect access control bit (CRWB) selects between a configure
(write) or interrogate (read) access to the channel provision RAM. Writing a
logic zero to CRWB triggers an indirect write operation. Data to be written is
taken from the Indirect Channel Data registers. Writing a logic one to CRWB
triggers an indirect read operation. The data read can be found in the Indirect
Channel Data registers.
