Section 18 Multi-Function Timer Pulse Unit (MTU)
(29) Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and
Operation is Restarted in Reset-Synchronous PWM Mode
Figure 18.113 shows an explanatory diagram of the case where an error occurs in reset-
synchronous PWM mode and operation is restarted in reset-synchronous PWM mode after re-
setting.
