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.
When provisioning a channel FIFO, all blocks pointers must be re-written to
properly initialize the FIFO.
Reserved:
The reserved bits must be set low for correct operation of the FREEDM-
84P672 device.
