2. PIN DESCRIPTION
SPI-3
SPI-3 is in Link mode or in PHY mode. The SPI-3 interface is configurable for
either Link or PHY mode. This configuration pertains to both the ingress and
egress paths. The device pin is given a generic name, and mapped to the
standard pin name according to the mode of the interface (Link or PHY).
