AX88796BLF / AX88796BLI

PME

O5/T5/8m

Wakeup Indicator: When programmed to do so, is asserted when the

AX88696B detects a wake event and is requesting the system to wake

up from the D1 sleep state. The polarity and buffer type of this signal

is programmable by BTCR (offset 15h)

2.3 Built-in PHY LED indicator pins group

Signal

Type

Pin No.

Description

I_FULL/COL

O5/8m

Full-Duplex/Collision Status. If this signal is low, it indicates

full-duplex link established, and if it is high, then the link is in

half-duplex mode. When in half-duplex and collision occurrence, the

output will be driven low for 80ms and driven high at minimum 80ms.

I_SPEED

O5/8m

Speed Status: If this signal is low, it indicates 100Mbps, and if it is

high, then the speed is 10Mbps.

I_LK/ACT

O5/8m

Link Status/Active: If this signal is low, it indicates link, and if it is

high, then the link is fail. When in link status and line activity

occurrence, this signal is pulsed high (LED off) for 80ms whenever

transmit or receive activity is detected. This signal is then driven low

again for a minimum of 80ms, after which time it will repeat the

process if TX or RX activity is detected.
