11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and
Operation is Restarted in Complementary PWM Mode: Figure 11.112 shows an explanatory
diagram of the case where an error occurs in reset-synchronous PWM mode and operation is
restarted in complementary PWM mode after re-setting.

1 to 10 are the same as in figure 11.110.
11. Disable channel 3 and 4 output with TOER.
12. Select the complementary PWM output level and cyclic output enabling/disabling with
TOCR.
13. Set complementary PWM. (The MTU cyclic output pin goes low.)
14. Enable channel 3 and 4 output with TOER.
15. Set MTU output with the PFC.
16. Operation is restarted by TSTR.
