REGISTERS

OVERVIEW

The register set is used to control and monitor the 10Base-T/100Base-TX Transceiver chip and can be accessed
through the MII management interface.
All changed bits will become active immediately. That includes the ' R eset' and ' R estart Auto-Negotiation' bits in the
Base Mode Control Register, BMCR. The software reset, the ' R eset' bit in BMCR, will reset the status registers and
all the state machines of the 10Base-T/100Base-TX Transceiver to their default values. All other registers will
maintain their pre-reset values. All required changes of the control registers necessary to obtain a wanted mode of
operation should be carried out before the ' R eset' bit is activated. In order to reset all the registers (including the
control registers) and all the state machines of the 10Base-T/100Base-TX transceiver chip to their default value, a
hardware or power-on reset has to take place.
