| 33 | * \section Purpose
|
| 34 | *
|
| 35 | * Interface for configuring and using Timer Counter (TC) peripherals.
|
| 36 | *
|
| 37 | * \section Usage
|
| 38 | * -# Optionally, use TC_FindMckDivisor() to let the program find the best
|
| 39 | * TCCLKS field value automatically.
|
| 40 | * -# Configure a Timer Counter in the desired mode using TC_Configure().
|
| 41 | * -# Start or stop the timer clock using TC_Start() and TC_Stop().
