Count Timing of External Trigger (TMCLE flag= 0)
When the TMCLE flag is set to "0" and the binary counter stops at the rising edge of the next count clock of
matching the binary counter and the compare/capture register, the binary counter is the setting value of the com-
pare/capture register + 1. When the activation trigger is fed to the pin again, the binary counter restarts to count
up.
