Default
This bit indicates the initial value of the LED2_BLINK field.
0b = LED2 is non-blinking.
1b = LED2 is blinking.
This bit indicates the initial value of the LED2_IVRT field.
0b = LED2 has an active low output.
1b = LED2 has an active high output.
This bit defines the LED2 blink mode:
0b = Slow rate.
1b = Fast rate.
This bit is reserved and should be set to 0b.
These bits represent the initial value of the LED2_MODE field,
which specifies the event, state, or pattern displayed on LED2
(LINK_100) output. A value of 0110b causes this to indicate
100 Mb/s operation.
This bit indicates the initial value of the LED0_BLINK field.
0b = LED0 is non-blinking (recommended).
1b = LED0 is blinking.
This bit indicates the initial value of the LED0_IVRT field.
0b = LED0 has an active low output.
1b = LED0 has an active high output.
This bit define the LED0 blink mode:
0b = Slow rate.
1b = Fast rate.
This bit is reserved and should be set to 0b.
These bits represent the initial value of the LED0_MODE field,
which specifies the event, state, or pattern displayed on LED0
(LINK_UP/Activity) output.
