LED Configuration PHY Address 01, Page 0, Register 30
NOTES:
1. When LED Blink mode is enabled the appropriate Led Invert bit should be set to zero.
2. The dynamic LED's modes (LINK/ACTIVITY and ACTIVITY) should be used with LED Blink mode enabled.
Interrupts
The 82577 maintains status bits (per interrupt cause) to reflect the source of the
interrupt request. System software is expected to clear these status bits once the
interrupt is being handled.
