Description
IPL1
Disable link down power saving mode
0: enable link down power saving mode (default)
1: disable link down power saving mode
LDPS_DIS is full duplex LED of port 0 after reset.
The function is valid only if pin 53 EXTMII_EN is pulled low.
Ability for detecting MLT3 (for 10 Mbps switch to 100 Mbps)
0: disable MLT3 detection ability (default)
1: enable MLT3 detection ability
MLT3_DET is link LED of port 7 after reset.
Broadcast storm enable
1: enable, 0: disable (default)
A port begins to drop packets if it receives broadcast packets
more than the threshold defined in MII register 31.9[15:14]
bq_stm_thr_sel [1:0] or EEPROM register 83[7:6].
Aggressive back off enable
IP178C/IP178CH
adopts modified (aggressive) back off
algorithm if this function is enabled. The maximum back off
period is limited to 8-slot time. It makes
IP178C/IP178CH
have
higher transmission priority in a collision event.
1: aggressive mode enable (default),
0: standard back off
It is link LED of port 4 after reset.
IPH1 Aging enable
1: enable 300s aging timer (default)
0: disable aging function
The function is valid only if pin 53 EXTMII_EN is pulled low.
IPL1
Select SCA function
Function selection for PIN_84
0: PIN_84 is LOW_10M_DIS (default)
1: PIN_84 is SCA_DIS
IPH1
/O
1: enable IEEE802.3x & back pressure (default),
0: disable IEEE802.3x & back pressure
The function is valid only if pin 53 EXTMII_EN is pulled low.
