DESCRIPTION

2

IOPU LED2 – Link Speed LED Indication.

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.
