42.6.3.4.1 Re-trigger Software Command or Event Action

A re-trigger command can be issued from software by using PDEC Command bits in Control B Set register (CTRLBSET.CMD = RETRIGGER) or when the re-trigger event action is configured in the Input Event Action bits in Event Control register (EVCTRL.EVACT = RETRIGGER) and an event is detected by hardware.

When the re-trigger command is detected during counting operation, the counter will be reloaded or cleared, depending on the counting direction (DIR). If the re-trigger command is detected when the counter is stopped, the counter will resume counting operation from the value in the COUNT register.
