- Memory Maps and Bit Descriptions -
SPI-3 Base Address: The 3 bit base address used to create the 8 bit
SPI-3 port address for both SPI-3 Input and SPI-3 output. The base
address is a 3 bit programmable value and is assigned to the most
significant 3 bits of the 8 bit SPI-3 address. Individual SPI-3 port address
are calculated by adding the (base address x 32) to the logical Ethernet
port number.
Reserved
SPI-3 Output Pause Cycle Time: The minimum Pause time between
transfers in SPI-3 clock cycles. Only used in PHY mode.
0 - 0 cycles
1 - 2 cycles
SPI-3 Output Single-PHY Enable: The SPI-3 Single-PHY mode enable
bit.
0 - Multi-PHY
1 - Single-PHY
SPI-3 Output Aggregation Mode Enable: The Aggregation Mode
Enable bit for SPI-3 Output.
0 - Normal mode
1 - Aggregate mode
SPI-3 Output Parity Mode: SPI-3 Output interface parity mode.
0 - Even parity
1 - Odd parity
SPI-3 Output Parity Enable: SPI-3 Output interface parity generation
enable bit.
0 - Parity generation not enabled
1 - Parity generation enabled
SPI-3 Output Mode: Bit to enable SPI-3 output mode.
0 - Burst (Chunk) Mode. In Burst mode, a configured number of bytes
(SPI-3 Output Burst Size) is sent across the SPI-3 interface before a re-
selection.
1 - Packet Mode. In Packet mode, a complete packet is sent across the
SPI-3 interface by a port before a port re-selection.
Reserved
SPI-3 Output PHY/Port Enable Per Port: SPI-3 Output PHY/Port
Enable bits for the 16 SPI-3 Output ports (one per port).
SPI-3 Output STPA Near Full Threshold: Output SPI-3 near full
threshold for de-assertion of STPA.
Reserved
