See
nINTSEL: On power-up or external reset, the mode of the nINT/TXER/TXD4
pin is selected.
Management Data Input/OUTPUT: Serial management data input/output.
Management Clock: Serial management clock.
Transmit/Receive Positive Channel 1.
Clock Input: Crystal connection or external clock input.
Clock Output: Crystal connection.
External Reset: Input of the system reset. This signal is active LOW.
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
Table 3.5 General Signals 32-QFN
