Bit 2—External Loop Back Mode (ELB): The value in this register is output directly to the
SH7615’s general-purpose external output pin (EXOUT). This is used for loopback mode
directives, etc., in the PHY-LSI, using the EXOUT pin.

Note: In order for PHY loopback to be implemented using this function, the PHY-LSI must have a
Bit 1—Duplex Mode (DM): Specifies the EtherC transfer method.
Bit 1: DM

Note: When internal loopback mode is specified (ILB = 1), full-duplex transfer (DM = 1) must be
Bit 0—Promiscuous Mode (PRM): Setting this bit enables all Ethernet frames to be received.
