This register contains data read from the channel provision RAM after an indirect
channel read operation or data to be inserted into the channel provision RAM in
an indirect channel write operation.
FPTR[10:0]:
The indirect FIFO block pointer (FPTR[10:0]) informs the partial packet buffer
processor about the circular linked list of blocks to use for a FIFO for the
channel. The FIFO pointer to be written to the channel provision RAM, in an
indirect write operation, must be set up in this register before triggering the
write. The FIFO pointer value can be any one of the block numbers
provisioned, by indirect block write operations, to form the circular buffer.
