   *  \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().
