
Crystal oscillator with an operating range of 1 MHz to 25 MHz.
12 MHz Internal RC (IRC) oscillator trimmed to 1 % accuracy that can optionally be
used as a system clock.
PLL allows CPU operation up to the maximum CPU rate without the need for a
high-frequency crystal. May be run from the system oscillator or the internal RC
oscillator.
Clock output function with divider that can reflect the system oscillator clock, IRC
clock, main clock, and Watchdog clock.
Real-Time Clock (RTC).
