Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Reset-Synchronous PWM Mode: Figure 10.109 shows an
explanatory diagram of the case where an error occurs in complementary PWM mode and
operation is restarted in reset-synchronous PWM mode.

Recovery in Reset-Synchronous PWM Mode
1 to 10 are the same as in Figure 10.105.
11. Set normal mode. (MTU output goes low.)
12. Disable channel 3 and 4 output with TOER.
13. Select the reset-synchronous PWM mode output level and cyclic output enabling/disabling
with TOCR.
14. Set reset-synchronous PWM.
15. Enable channel 3 and 4 output with TOER.
16. Set MTU output with the PFC.
17. Operation is restarted by TSTR.
