Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in Reset-Synchronous PWM Mode: Figure 11.90 shows an explanatory diagram of the case
where an error occurs in normal mode and operation is restarted in reset-synchronous PWM mode
after re-setting.

1 to 13 are the same as in figure 11.89.
14. Select the reset-synchronous PWM output level and cyclic output enabling/disabling with
TOCR.
15. Set reset-synchronous PWM.
16. Enable channel 3 and 4 output with TOER.
17. Set MTU output with the PFC.
18. Operation is restarted by TSTR.
