This register contains data read from the transmit block pointer RAM after an
indirect block read operation or data to be inserted into the transmit 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 transmit 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 channel FIFO buffer.
FPTR[10:0] reflects the value written until the completion of a subsequent
indirect block read operation.
