Bits 13 to 8: Transmit FIFO Almost Empty Level (TFAE[5:0]) – In POS-PHY packet processing mode, these six
bits indicate the maximum number of four byte groups that can be stored in the Transmit FIFO for it to be
considered "almost empty". E.g., a value of 30 (1Eh) results in the FIFO being "almost empty" when it contains 120
(78h) bytes or less. In cell processing mode, these bits are ignored.
Bits 5 to 0: Transmit FIFO Almost Full Level (TFAF[5:0]) – In POS-PHY packet processing mode, these six bits
indicate the maximum number of four byte groups that can be available in the Transmit FIFO for it to be considered
"almost full". E.g., a value of 30 (1Eh) results in the FIFO being "almost full" when it has 120 (78h) bytes or less
available. In cell processing mode, TFAF[5:2] are ignored, and TFAF[1:0] indicate the maximum number of cells
that can be available in the Transmit FIFO for it to be considered "almost full".

Bits 4 to 0: Transmit FIFO System Port Address (TPA[4:0]) – These five bits set the Transmit FIFO system
interface port address used to poll the Transmit FIFO for fill status, and select it for data transfer. In Level 2 mode,
if bits TPA[4:0] are set to a value of 1Fh, the port is disabled.
