CHAN[4:0]:

The indirect channel number bits (CHAN[4:0]) 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.

BUSY:

The indirect access status bit (BUSY) reports the progress of an indirect

access. BUSY is set high when this register is written to trigger an indirect

access, and will stay high until the access is complete. At which point, BUSY

will be set low. This register should be polled to determine when data from an

indirect read operation is available in the RHDL Indirect Channel Data #1 and

#2 registers or to determine when a new indirect write operation may

commence.
