11.0 GPSI (7WS) Interface
11.1 GPSI connection
The 10/100 RMII ethernet port can function in GPSI (7WS) mode when the corresponding TXEN pin is strapped low
with a 1 K pull down resistor. In this mode, the TXD[0], TXD[1], RXD[0] and RXD[1] serve as TX data, TX clock, RX
data and RX clock respectively. The link status and collision from the PHY are multiplexed and shifted into the
switch device through external glue logic. The duplex of the port can be controlled by programming the ECR
register. The GPSI interface can be operated in port based VLAN mode only.
