This section lists and describes the signals that connect off chip
12.2.1
Theses pins provides operating voltage (V
allows the supply voltage to the XOSC to use an independent bypass capacitor.
12.2.2
These pins provide the interface for either a crystal or a 1.8V CMOS compatible clock to control the
internal clock generator circuitry. EXTAL is the external clock input or the input to the crystal oscillator
amplifier. XTAL is the output of the crystal oscillator amplifier. The MCU internal system clock is derived
