Pin Function
Test Enable
For normal operation, 1K ohm pull-down this pin to ground.
Scan Test Scan MUX Enable
For normal operation, 1K ohm pull-down this pin to ground.
Port 1 and Port 2 LED indicators
Notes:
1. Link = On; Activity = Blink; Link/Act = On/Blink; Full Dup/Col = On/Blink;
Full Duplex = On (Full duplex); Off (Half duplex)
Speed = On (100BASE-T); Off (10BASE-T)
2. P1LED3 is pin 27. P2LED3 is pin 22.
Digital ground
3.3V digital V
Ready Return Not:
For VLBus-like mode: Asserted by the host to complete synchronous read cycles. If
the host doesn’t connect to this pin, assert this pin.
For burst mode (32-bit interface only): Host drives this pin low to signal waiting
states.
Bus Interface Clock
Local bus clock for synchronous bus systems. Maximum frequency is 50MHz.
This pin should be tied Low or unconnected if it is in asynchronous mode.
No connect.
No connect.
Synchronous Ready Not
Ready signal to interface with synchronous bus for both EISA-like and VLBus-like
extended accesses.
For VLBus-like mode, the falling edge of this signal indicates ready. This signal is
synchronous to the bus clock signal BCLK.
For burst mode (32-bit interface only), the KSZ8862M drives this pin low to signal
wait states.
