| /// !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(). | |
