Descriptions
If user put 93C66 then data put in Bank0. User can write
chip register by 93C66 timing.
User must assert one SK cycle when CS at idle stage when
write chip internal register.

Descriptions
LINK/Activity LED[4:0].
Active low
“1” indicates no link activity on cable
“0” indicates link okay on cable, but no activity and signals
on idle stage.
“Blinking” indicates link activity on cable.
Duplex/Collision LED[4:3].
Active low
“1” for half-duplex and “blinking” for collision indication
“0” for full-duplex indication
Duplex/Collision LED2.
Active low
“1” for half-duplex and “blinking” for collision indication
“0” for full-duplex indication
Setting
BPEN: At power-on-reset, latched as Back Pressure setting
“1” to enable Back-Pressure (defaulted), “0” to disable Back
Pressure.
At power-on-reset, latched as Back Pressure setting “1” to
enable Back-Pressure (defaulted), “0” to disable Back
Pressure.
Duplex/Collision LED1.
Active low
“1” for half-duplex and “blinking” for collision indication
“0” for full-duplex indication
Setting
PHYAS1: Power on Reset latch value combine with TXEN.
Internal pull down. Check pin 66.
Duplex/Collision LED0.
Active low
“1” for half-duplex and “blinking” for collision indication
“0” for full-duplex indication
Setting
ANEN: On power-on-reset, latched as Auto Negotiation
capability for all ports.
“1” to enable Auto Negotiation ( defaulted by pulled up
internally ),
“0” to disable Auto Negotiation.
Speed LED[4:0].
Used to indicate corresponding port’s
speed status. “0” for 100Mb/s, “1” for 10Mb/s
