/// !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(). | |
