IP101G-DS-R01
5.4 LED Mode Configuration
IP101G provides 2 LED operation modes,
LED Mode 1
(default):
Table 6 LED Mode 1 Function
LED
Function
LED0
Link status: Active indicates the link has established
LED1
Duplex operation: Active indicates full duplex
LED2
10BT/ACT: Active indicates 10Mbps connection has established, and blinking while
TX/RX events occur.
LED3
100BT/ACT: Active indicates 100Mbps connection has established, and blinking while
TX/RX events occur.
LED Mode 2
(could be set by pulling up pin CRS/LEDMOD with a 4.7K resistor):
Table 7 LED Mode 2 Function
LED
Function
LED0
Link/ACT: Active indicates the link has established, and blinking while TX/RX events
occur.
LED1
Duplex/COL: Active indicates full duplex, and blinking while collision events occur.
LED2
10BT: Active indicates 10Mbps connection has established
LED3
100BT: Active indicates 100Mbps connection has established
5.5 LED Blink Timing
Table 8 LED Blink Timing
LED mode
Blinking speed
Active LED blink
On 26ms -> Off 78ms -> On 26ms -> Off 78ms …
Collision LED blink
On 26ms -> Off 78ms -> On 26ms -> Off 78ms …
5.6 Repeater Mode
To enter Repeater mode, one can set 1 to bit 2 of Register 16 will allow IP101G to enter Repeater mode.
If IP101G is used in repeater, CRS will be high if IP101G is in a process of receiving packets. While
IP101G is used in a network interface card, CRS will be generated in both transmitting and receiving
packets.
5.7 Interrupt
IP101G provides 4 kinds of interrupt function: speed change, duplex change, link change and arbiter
state change. Interrupt masks could be selected by Reg 17, and an active low interrupt will be sent from
INTR or INTR_32 pin when event occurs.
5.8 Miscellaneous
ISET pin should be connected to GND via a 6.19K ohm resistor with 1% accuracy to ensure a correct
driving current for transmit DAC.
