This presentation walks you through the features and specs of the most integrated solution for CAN node applications. Details @ http://www.freescale.com/S12magniV

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.

Here is a SW example demonstrating measurement of the bandgap voltage featured on a microcontroller. The bandgap voltage is routed to an internal ATD channel. ATD converter measures the input voltage and stores it to a variable located in Flash memory. The SW example project is made in CodeWarrior v5.1 for MC9S12XEP100 device.
