Workflow

1.

Enable the TC module's waveform pin:

ioport_set_pin_mode(PIN_TC_WAVEFORM, PIN_TC_WAVEFORM_MUX);
ioport_disable_pin(PIN_TC_WAVEFORM);

2.
Initialize the waveform channel to the following:
- Output frequency of 178Hz, with a duty-cycle of 30%
- Use TC_CMR_TCCLKS_TIMER_CLOCK4, with a divisor of 128
```
tc_waveform_initialize();
```
