12.3.2 MC68HC912D60A Oscillator Design Guidelines
Proper and robust operation of the oscillator circuit requires excellent
board layout design practice. Poor layout of the application board can
contribute to EMC susceptibility, noise generation, slow starting
oscillators, and reaction to noise on the clock input buffer. In addition to
published errata for the MC68HC912D60A, the following guidelines
must be followed or failure in operation may occur.
