• CPCDIS: Counter Clock Disable with RC Compare (Code Label TC_CPCDIS)
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
Note:
• ENETRG: External Event Trigger Enable (Code Label TC_ENETRG)
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.
• CPCTRG: RC Compare Trigger Enable (Code Label TC_CPCTRG)
0 = RC Compare has no effect on the counter and its clock.
1 = RC Compare resets the counter and starts the counter clock.
• WAVE = 1 (Code Label TC_WAVE)
0 = Waveform Mode is disabled (Capture Mode is enabled).
1 = Waveform Mode is enabled.
• ACPA: RA Compare Effect on TIOA
