• 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:
• 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.
