Off-chip resister. Must be connected 12.1K ohm ± 1% to ground.
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.
Speed Status: If this signal is low, it indicates 100Mbps, and if it is
high, then the speed is 10Mbps.
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.
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)
EEPROM Chip Select: EEPROM chip select signal.
EEPROM Clock: Signal connected to EEPROM clock pin.
EECS, EECK can load BUS type setting during power on reset cycle.
