(28) Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and
Operation is Restarted in Reset-Synchronous PWM Mode: Figure 12.124 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.
