Register 0x210: RHDL Indirect Block Select
This register provides the block number used to access the block pointer RAM. Writing to this
register triggers an indirect block register access.
BLOCK[11:0]
BRWB
BBUSY
The indirect block number (BLOCK[11:0]) indicates the block to be configured or
interrogated in the indirect access.
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.
The indirect access status bit (BBUSY) reports the progress of an indirect access. BBUSY 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, BBUSY 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.
