The restart operation is explained.
Restart operation is as follows:

Regardless of whether PWM operation or one-shot operation is being performed, the second or subsequent
trigger does not influence operation (does not cause restart) if the restart enable bit (PCN:RTRG) is "0"
(restart disabled). However, if, in the case of one-shot operation, the second or subsequent trigger occurs
after one-shot operation, it works as a restart trigger.
