Datasheet

Document Number: 302875-005

Revision Date: 27-Oct-2005

• During a software reset, bit settings in Table 45, “Auto-Negotiation Advertisement Register -

Address 4, Hex 4” on page 79 are not re-read from the LXT972M Transceiver configuration

pins. Instead, the bit settings revert to the values that were read in during the last hardware

reset. Therefore, any changes to pin values made since the last hardware reset are not detected

during a software reset.

• During a software reset, registers are available for reading. To see when the LXT972M

Transceiver has completed reset, the reset bit can be polled (that is, Register bit 0.15 = 0).

For pin settings used during a hardware reset, see Section 5.4.4, “Hardware Configuration

Settings”. During a hardware reset, configuration settings for auto-negotiation and speed are read

in from pins, and register information is unavailable for 1 ms after de-assertion of the reset.
