41.6.2.4.3 Re-Trigger Command and Event Action

A re-trigger command can be issued from software by using TCC Command bits in the Control B Set register (CTRLBSET.CMD = 0x1, RETRIGGER) or from an event when the re-trigger event action is configured in the Input Event 0/1 Action bits in Event Control register (EVCTRL.EVACTn = 0x1, RETRIGGER).

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