In the ZIP file you can find two CodeWarrior projects, one for S12ZVM and other for S12ZVL device, demonstrating the trimming of Autonomous Clock (ACLK - trimmable internal RC-Oscillator) which can be selected as clock source for some CPMU features.
Also the Autonomous Periodical Interrupt feature using the trimmed ACLK as a clock source is demonstrated too in this SW example.
