| * \section Purpose | |
| * | |
| * Interface for configuring and using Timer Counter (TC) peripherals. | |
| * | |
| * \section Usage | |
| * -# Optionally, use tc_find_mck_divisor() 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(). | |
