Section 9 Ethernet Controller (EtherC)
Bit 0—Illegal Carrier Detection (ICD): Indicates that PHY-LSI has detected an illegal carrier on
the line. This bit is cleared by writing 1 to it. Writing 0 to this bit has no effect.
Bit 0: ICD

Note: If a change in the signal input from the PHY-LSI occurs before the software recognition
9.2.3
This register enables or disables the interrupt sources indicated by the EtherC status register. Each
bit in this register enables or disables the interrupt indicated by the corresponding bit in the EtherC
status register.
Bits 31 to 3—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 2— LINK Signal Changed Interrupt Permission (LCHNGIP): Controls interrupt notification
by the LINK Signal Changed bit.
Bit 2: LCHNGIP
