* \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().
