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(). |
