Description
Input Crystal/Resonator or External Clock Input
Input to the on-chip oscillator and the internal clock generators. The internal
clock generators provide the peripheral clocks, CPU clock, and CLKOUT
signal. When using an external clock source instead of the on-chip oscillator,
connect the clock input to XTAL1. The external clock signal must meet the VIH
specification for XTAL1.
Inverted Output for the Crystal/Resonator
Output of the on-chip oscillator inverter. Leave XTAL2 floating when the design
uses an external clock source instead of the on-chip oscillator.
