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
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.
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.
