Chapter 5 Oscillator (OSCV2)
5.2.1
These pins provide the operating voltage (V
allows the supply voltage to the OSCV2 to be independently bypassed.
5.2.2
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. All the MCU internal system clocks are derived from
the EXTAL input frequency. In full stop mode (PSTP = 0) the EXTAL pin is pulled down by an internal
resistor of typical 200 kΩ.
