Logic outputs supply voltage (pull-up reference)
Internal 3 V voltage regulator output and 3.3 V external
logic supply
Oscillator pin 1. To connect an external oscillator or clock
source. If this pin is UNUSED, it should be connected to
ground.
Oscillator pin 2. To connect an external oscillator. When
the internal oscillator is used this pin can supply a
2/4/8/16 MHz. If this pin is UNUSED, it should be left
floating.
Charge pump oscillator output
