Theses pins provides operating voltage (V
allows the supply voltage to the XOSC to be independently bypassed.
3.2.2
These pins provide the interface for either a crystal or a 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 from the
