I am new to Freescale microcontrollers and I managed the Timer to work and its interrupting. But inorder to do more complicated things with it that I intend on doing, I need to understand what and how it works. Kindly answer a few question I have or please provide me a link to some documentation that gives a somewhat detailed description of the process.

1. What is a PulseAccumulator and what is it used for?

2. In MSP430 microcontrollers I worked on, the documentation clearly explained its three counter modes: Up Counter, Down Counter and UP-Down counter. I know for sure HCS12 has these and probably much more, but where can I get some clearly wriiten info on how it works(I went through all the relevent datasheets on Freescale website without luck)

Thanks a million,
