The oscillator module provides the reference clock for the MCU system
and bus. Two types of oscillator modules are available:
•
•
MC68HC908xxx— built-in oscillator module (X-tal oscillator) that
requires an external crystal or ceramic-resonator. This option also
allows an external clock that can be driven directly into OSC1.
MC68HRC908xxx — built-in oscillator module (RC oscillator) that
requires an external RC connection only.
