Low drop-out regulator output voltage. This pin
requires an external capacitor between the pin and
GND of 1 µF or greater. When the on-chip LDO is
used to provide power to the logic, the LDO pin must
also be connected to the VDDC pins at the board
level in addition to the decoupling capacitor(s).
Ethernet LED 0.
Ethernet LED 1.
MDIO of the Ethernet PHY.
No connect. Leave the pin electrically
unconnected/isolated.

Non-maskable interrupt.
Main oscillator crystal input or an external clock
reference input.
Main oscillator crystal output. Leave unconnected
when using a single-ended clock source.
GPIO port A bit 0.
