• 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. In this case, the selected external event only controls the TIOA
output.
1 = the external event resets the counter and starts the counter clock.
• WAVSEL: Waveform Selection
• WAVE: Waveform Mode
0 = Waveform Mode is disabled (Capture Mode is enabled).
1 = Waveform Mode is enabled.
• ACPA: RA Compare Effect on TIOA
