7.1 SPI-3 Loopback
In this mode, the contents of the SPI-3 ingress buffers are directly transferred
to the SPI-3 egress buffers. All data and error information received on an ingress
interface of a SPI-3 physical port is transmitted on the egress interface of the same
SPI-3 physical port.
Chip Counters Memory
A SPI-3 physical port loop back is supported on each of the SPI-3 interfaces.
