System reset input, low active.
50MHz system clock input
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.
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.
Port0 speed indicator, input from PHY.
SPD0 input low: 100M , input high: 10M.
Port1 speed indicator, input from PHY.
SPD1 input low: 100M , input high: 10M.
Port2 speed indicator, input from PHY.
SPD2 input low: 100M , input high: 10M.
Port3 speed indicator, input from PHY.
SPD3 input low: 100M , input high: 10M.
Port4 speed indicator, input from PHY.
SPD4 input low: 100M , input high: 10M.
Port5 speed indicator, input from PHY.
SPD5 input low: 100M , input high: 10M.
, its serial out data sequence is : ( first bit be shifted out is from b00, and
end of burst bit is b23)
data serial shift out. Every clock burst have 24 cycles ( period : 160 ns),
and the clock burst will be repeated with every 42ms.
