Memory Maps and Bit Descriptions
SPI-3 Input Configuration
Reserved
SPI-3 Input Single-PHY Enable: The SPI-3 Single-PHY mode enable
bit.
0 - Multi-PHY
1 - Single-PHY
SPI-3 Input Aggregation Mode Enable: The Aggregation Mode Enable
bit for SPI-3 Input.
0 - Normal mode
1 - Aggregate mode
Aggregate Mode TAG Position: The Ethernet Aggregate Mode Tag
Position. This indicates the byte position in the Aggregate Tag word (4
bytes long), which indicates the PHY number of the packet.
SPI-3 Input Parity Mode: SPI-3 Input interface parity mode.
0 - Even parity
1 - Odd parity
SPI-3 Input Parity Enable: SPI-3 Input interface parity checking enable
bit.
0 - Parity checking not enabled
1 - Parity checking enabled
Reserved
SPI-3 Input PHY/Port Enable Per Port: SPI-3 Input PHY/Port Enable
bits for the 16 SPI-3 Input ports (one per port). Bit 0 = Port 0, Bit 1 = Port
1..... Bit 15 = Port 15.
Reserved
SPI-3 Input STPA Low Threshold: Input SPI-3 near full low threshold
for assertion of STPA. Once STPA is de-asserted because the Egress
FIFO reached the SPI-3 high threshold (SISHT), STPA will be asserted
when the Egress FIFO reaches the STPA low threshold. This allows for
a hysteresis in the STPA signal. For a bus width of 8 bits, the value is
based on bytes. For a bus width of 16 bits, 2 bytes and a bus width of 32
bits, 4 bytes. Minimum value is 2.
