Oscillator (OSC) Module
11.1 Introduction
The oscillator (OSC) module is used to provide a stable clock source for the MCU system and bus.
The OSC shares its pins with general-purpose input/output (I/O) port pins. See
location of these shared pins. The OSC2EN bit is located in the port A pull enable register (PTAPUEN)
on this MCU. See
11.2 Features
The bus clock frequency is one fourth of any of these clock source options:
11.3 Functional Description
The oscillator contains these major subsystems:
Freescale Semiconductor
1. Internal oscillator: An internally generated, fixed frequency clock, trimmable to ± 0.4%. There are
2. External oscillator: An external clock that can be driven directly into OSC1.
3. External RC: A built-in oscillator module (RC oscillator) that requires an external R connection only.
4. External crystal: A built-in XTAL oscillator that requires an external crystal or ceramic-resonator.

three choices for the internal oscillator,12.8 MHz, 8 MHz, or 4 MHz. The 12.8-MHz internal
oscillator is the default option out of reset.
The capacitor is internal to the chip.
There are three crystal frequency ranges supported, 8–32 MHz, 1–8 MHz, and 32–100 kHz.
