Low drop-out regulator output voltage. This pin

requires an external capacitor between the pin and

GND of 1 ÂµF or greater. The LDO pin must also be

connected to the VDDC pins at the board level in

addition to the decoupling capacitor(s).

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.
