This register contains data read from the channel provision RAM after an indirect
read operation or data to be inserted into the channel provision RAM in an
indirect write operation.
FPTR[10:0]:
The indirect FIFO block pointer (FPTR[10:0]) identifies one of the blocks of
the circular linked list in the partial packet buffer used in the logical FIFO of
the current 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 blocks
provisioned to form the circular buffer.
