(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.

Recovery in Reset-Synchronous PWM Mode
1 to 10 are the same as in figure 18.110.
11. Set MTU output with the PFC.
12. Operation is restarted by TSTR.
13. The reset-synchronous PWM waveform is output on compare-match occurrence.
