Register 0x214: RHDL Indirect Block Data
This register contains data read from the block pointer RAM after an indirect block read operation
or data to be inserted into the block pointer RAM in an indirect block write operation.
BPTR[11:0]
The indirect block pointer (BPTR[11:0]) configures the block pointer of the block specified by
the Indirect Block Select register. The block pointer to be written to the block pointer RAM, in
an indirect write operation, must be set up in this register before triggering the write. The block
pointer value is the block number of the next block in the linked list. A circular list of blocks
must be formed in order to use the block list as a receive channel FIFO buffer. BPTR[11:0]
reflects the value written until the completion of a subsequent indirect block read operation.
When provisioning a channel FIFO, all block pointers must be re-written to properly initialize
the FIFO.
