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[10:0]:
The indirect block pointer (BPTR[10:0]) 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[10:0] 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.
