 *  \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().
