Ball Function
Test Enable
For normal operation, pull-down this ball to ground.
Scan Test Scan Mux Enable
For normal operation, pull-down this ball to ground.
Port 1 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 ball A4.
Ready Return Not:
For VLBus-like mode: Asserted by the host to complete synchronous read
cycles. If the host doesn’t connect to this ball, assert this ball.
Bus Interface Clock
Local bus clock for synchronous bus systems. Maximum frequency is 50MHz.
This ball should be tied Low or unconnected if it is in asynchronous mode.
Power Management Event Not
When asserted (Low), this signal indicates that a power management event has
occurred in the system when a wake-up signal is detected by KSZ8841M.
Synchronous Ready Not
Ready signal to interface with synchronous bus for both EISA-like and VLBus-
like extend accesses.
For VLBus-like mode, the falling edge of this signal indicates ready. This signal
is synchronous to the bus clock signal BCLK.
Interrupt
Active Low signal to host CPU to indicate an interrupt status bit is set, this ball
need an external 4.7K pull-up resistor.
