FRAME ENGINE AND DATA LINK MANAGER
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.
