• CPCDIS: Counter Clock Disable with RC Compare
0: Counter clock is not disabled when counter reaches RC.
1: Counter clock is disabled when counter reaches RC.
• EEVTEDG: External Event Edge Selection
• EEVT: External Event Selection
Signal selected as external event.
Note: 1. If TIOB is chosen as the external event signal, it is configured as an input and no longer generates waveforms and
subsequently no IRQs.
• ENETRG: External Event Trigger Enable
0: The external event has no effect on the counter and its clock.
1: The external event resets the counter and starts the counter clock.
Note: Whatever the value programmed in ENETRG, the selected external event only controls the TIOA output and TIOB if not used as
input (trigger event input or other input used).
• WAVSEL: Waveform Selection
• WAVE: Waveform Mode
0: Waveform Mode is disabled (Capture Mode is enabled).
1: Waveform Mode is enabled.
