BLOCK[8:0]:

The indirect block number (BLOCK[8:0]) indicate the block to be configured

or interrogated in the indirect access.

BRWB:

The block indirect access control bit (BRWB) selects between a configure

(write) or interrogate (read) access to the block pointer RAM. Writing a logic

zero to BRWB triggers an indirect block write operation. Data to be written is

taken from the Indirect Block Data register. Writing a logic one to BRWB

triggers an indirect block read operation. The data read can be found in the

Indirect Block Data register.

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 Block Data register or

to determine when a new indirect write operation may commence.
