Pin Function
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
LED is ON when output is LOW; LED is OFF when output is HIGH.
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.

Power Management Event: It is asserted (low or high depends on polarity set in PMECR
register) when one of the wake-on-LAN events is detected by KSZ8851M. The
KSZ8851M is requesting the system to wake up from low power mode.
No Connect.
Interrupt
Active Low signal to host CPU to indicate an interrupt status bit is set.
Local Device Not
Active Low output signal, asserted when AEN is Low and A7-A1 decode to the
KSZ8851M right address register. LDEVN is a combinational decode of the Address and
AEN signal.
