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 THDL Indirect Block Data register or
to determine when a new indirect write operation may commence.
