* \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(). | |
