* \section Purpose
*
* Interface for configuring and using Timer Counter (TC) peripherals.
*
* \section Usage
* -# Optionally, use TC_FindMckDivisor() to let the program find the best
* TCCLKS field value automatically.
* -# Configure a Timer Counter in the desired mode using TC_Configure().
* -# Start or stop the timer clock using TC_Start() and TC_Stop().
