This register provides the channel number used to access the receive channel
provision RAM. Writing to this register triggers an indirect channel register
access.
CHAN[9:0]:
The indirect channel number bits (CHAN[9:0]) indicate the receive 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 receive 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.
