I/O
Descriptions
I/O LED display serial data out; mapping for LEDCLK signal’s burst clock
, its serial out data sequence is : ( first bit be shifted out is from b00, and
end of burst bit is b23)
b00: port0 partition b08: 10hub_col
b16: port0 rx_activity
b01: port1 partition b09: 100hub_col
b17: port1 rx_activity
b02: port2 partition b10: asram_test_fail b18: port2 rx_activity
b03: port3 partition b11: port3 partition b19: port3 rx_activity
b04: port4 partition b12: port4 partition b20: port4 rx_activity
b05: port5 partition b13: port5 partition b21: port5 rx_activity
b06: port6 partition b14: port6 partition b22: port6 rx_activity
b07: port7 partition b15: port7 partition b23: port7 rx_activity
LEDCLK
I/O LED display clock signal, the signal is a discontinued clock for LED
125
data serial shift out. Every clock burst have 24 cycles ( period : 160 ns),
and the clock burst will be repeated with every 42ms.

I/O
Descriptions
I System reset input, low active.
I 50MHz system clock input
I/O MII management clock inout
I/O MII management data inout
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
port7.
I When up_link switch port enabling, this pin is port7’s full_deplex indi-
cator, input from PHY. When hign , indicate port7 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.
I Port5 speed indicator, input from PHY.
SPD5 input low: 100M , input high: 10M.
