+/// !Purpose
+///
+/// API for configuring and using Timer Counter (TC) peripherals.
+///
+/// !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().
