Test Enable
For normal operation, pull-down this pin to ground.
Scan Test Scan Mux Enable
For normal operation, pull-down this pin 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 pin 27.

Digital ground
3.3V digital V
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.
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.
