Configure the TCC

1.
Create a module software instance structure for the TCC module to store the TCC driver state while it is in use.
```
struct tcc_module tcc_instance;
```
Note: This should never go out of scope as long as the module is in use. In most cases, this should be global.
2.
Create a TCC module configuration struct, which can be filled out to adjust the configuration of a physical TCC peripheral.
```
struct tcc_config config_tcc;
```
3.
Initialize the TCC configuration struct with the module's default values.
```
tcc_get_config_defaults(&config_tcc, CONF_PWM_MODULE);
```
Note: This should always be performed before using the configuration struct to ensure that all values are initialized to known default settings.

Alter the TCC settings to configure the counter width, wave generation mode and the compare channel 0 value.

config_tcc.counter.clock_prescaler = TCC_CLOCK_PRESCALER_DIV1024;
config_tcc.counter.period = 0x1000;
config_tcc.compare.channel_function[CONF_TCC_CAPTURE_CHANNEL] =
        TCC_CHANNEL_FUNCTION_CAPTURE;
config_tcc.compare.wave_generation = TCC_WAVE_GENERATION_SINGLE_SLOPE_PWM;
config_tcc.compare.wave_polarity[CONF_PWM_CHANNEL] = TCC_WAVE_POLARITY_0;
config_tcc.compare.match[CONF_PWM_CHANNEL] = compare_values[2];

Alter the TCC settings to configure the PWM output on a physical device pin.

config_tcc.pins.enable_wave_out_pin[CONF_PWM_OUTPUT] = true;
config_tcc.pins.wave_out_pin[CONF_PWM_OUTPUT]        = CONF_PWM_OUT_PIN;
config_tcc.pins.wave_out_pin_mux[CONF_PWM_OUTPUT]    = CONF_PWM_OUT_MUX;

Configure the TCC module with the desired settings.

tcc_init(&tcc_instance, CONF_PWM_MODULE, &config_tcc);

Configure and enable the desired events for the TCC module.

struct tcc_events events_tcc = {
    .input_config[0].modify_action = false,
    .input_config[1].modify_action = false,
    .output_config.modify_generation_selection = false,
    .generate_event_on_channel[CONF_PWM_CHANNEL] = true,
    .on_event_perform_channel_action[CONF_TCC_CAPTURE_CHANNEL] = true
};
tcc_enable_events(&tcc_instance, &events_tcc);
