MC68HC912D60A — Rev. 3.1
Freescale Semiconductor
There are the following primary differences between the previous
Colpitts (‘A’) and new Pierce (‘P’) oscillator configurations:

Figure 12-4. MC68HC912D60P Pierce Oscillator Architecture
Oscillator architecture was changed from Colpitts to Pierce.
Hysteresis was added to the clock input buffer to reduce sensitivity
to noise.
The bias current to the amplifier was optimized for less process
variation.
