Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
ENERGYON Interrupt
Value Description
1 An interrupt has been generated due to the ENON bit being set
in the MR17 register.
0 No interrupt.
This bit is cleared by reading the value.
Auto-Negotiation Complete Interrupt
