Register 0x3A4: THDL Indirect Block Data
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[11:0]
The indirect block pointer (BPTR[11:0]) 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[11:0] 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.
