I/O
Descriptions
I Up_link switch port enabling : one of internal two_port switch port will
connect to 100M_hub domain, and another port will redirect to RMII
port4.
I When up_link switch port enabling, this pin is port4’s full_deplex indi-
cator, input from PHY. When hign , indicate port4 in running on
full_duplex mode. When low, indicate on half_duplex mode.
I Port0 speed indicator, input from PHY.
SPD0 input low: 100M , input high: 10M.
I Port1 speed indicator, input from PHY.
SPD1 input low: 100M , input high: 10M.
I Port2 speed indicator, input from PHY.
SPD2 input low: 100M , input high: 10M.
I Port3 speed indicator, input from PHY.
SPD3 input low: 100M , input high: 10M.
I Port4 speed indicator, input from PHY.
SPD4 input low: 100M , input high: 10M.
