DESCRIPTION

EDSHORT

Energy Detect Short detection mode

0 = Normal detect mode

1 = Short detect mode

FASTRIP

10BASE-T fast mode

0 = normal operation

1 = activates PHYT_10 test mode

EDPWRDOWN

Enable the Energy Detect Power-Down mode

0 = Energy Detect Power-Down is disabled

1 = Energy Detect Power-Down is enabled

ED Power Down Mode

Select energy detect power down mode

0 = ED power down mode without NLP transmission

1 = ED power down mode with NLP transmission

RESERVED

Speed Optimize Enable

0 = Disable Speed Optimize

1 = Enable Speed Optimize

Note: Refer to Section 3.9.7, "Speed Optimizer," on page 38 for additional

information.

AutoNeg NP Enable

0 = Next page is disabled in the auto-negotiation process

1 = Next page is enabled in the auto-negotiation process

Auto MDIX Disable

0 = Auto Xover is enabled

1 = Auto Xover is disabled selection is done manually

Auto Next Page Disable

Setting this bit disables automatic next page exchange in 1000BASE-T.

Advertising of next pages then depends on the value of the Next Page bit of

the Auto Negotiation Advertisement Register. In this case, if Next Page is

cleared, only the base page is sent.

0 = Normal operation

1 = Automatic next page is disabled

RESERVED

ENERGYON

This bit indicates whether energy is detected on the line. It is reset to â1â by

a hardware reset. When a software reset is asserted, this bit is cleared. If

this bit was set prior to a software reset, it will cause the INT7 bit of the

Interrupt Source Flags Register to be set. Therefore, after a software or

hardware reset, the INT7 bit should be cleared by writing a â1â to it.

Refer to Section 3.5, "Interrupt Management," on page 26 for additional

ENERGYON information.
