Low drop-out regulator output voltage. This pin
requires an external capacitor between the pin and
GND of 1 µF or greater. The LDO pin must also be
connected to the VDDC pins at the board level in
addition to the decoupling capacitor(s).
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.
