IOPU

LED2 – Link Speed LED Indication.

nINTSEL

 

 

See Section 5.3.7 for a description of LED modes.

 

 

 

nINTSEL: On power-up or external reset, the mode of the nINT/TXER/TXD4

 

 

 

pin is selected.

 

 

 

„ When LED2/nINTSEL is floated or pulled to VDDIO, nINT is selected for

 

 

 

operation on pin nINT/TXER/TXD4 (default).

 

 

 

„ When LED2/nINTSEL is pulled low to VSS through a resistor, TXER/TXD4

 

 

 

is selected for operation on pin nINT/TXER/TXD4.

 

 

 

„ See Section 4.10 for additional information.
