Preliminary Data Sheet

Speed

Used by the physical layer management polling entity to configure physical layer’s

speed mode when EEPROM forced modes are selected. Additionally this bit can be

used to directly force the internal speed mode.

00 – 10M

01 – 100M

10 – 1000M

Duplex

Used by the physical layer management polling entity to configure physical layer’s

duplex mode when EEPROM forced modes are selected. Additionally this bit can

be used to directly force the internal duplex mode.

ForceLnk

Setting this bit to '1' will force the internal polled link status of the corresponding port

to “ON”. Default is ‘0’.

TxDisable

Setting this bit to '1' will disable the transmission MAC device, thus inhibiting

transmission on the corresponding port. Default is ‘0’.

RxDisable

Setting this bit to '1' will disable the receiving MAC device, thus inhibiting receiving

on the corresponding port. Default is ‘0’.

DisFdxFCTx

Setting this bit to '1' will disable flow control operation for full duplex mode on

transmit side (transmission of pause frames). Default is ‘0’.

DisFdxFCRx

Setting this bit to '1' will disable flow control operation for full duplex mode on

receive side (pausing frame transmission). Default is ‘0’.

DisBackPres

Setting this bit to '1' will disable flow control for half duplex mode (backpressure).

Default value is its corresponding DisBkPr pin value.

PortPriorityEn

Setting this bit to '1' will force the corresponding port to the priority set within the

PortPriority field, otherwise the pin configuration will be used.

PortPriority

This bit will set one of the four priority classes on the corresponding port.

Confidential.
