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.
