Section 18 Multi-Function Timer Pulse Unit (MTU)
(12) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in Reset-Synchronous PWM Mode
Figure 18.96 shows an explanatory diagram of the case where an error occurs in PWM mode 1
and operation is restarted in reset-synchronous PWM mode after re-setting.

1 to 14 are the same as in figure 18.95.
15. Select the reset-synchronous PWM output level and cyclic output enabling/disabling with
TOCR.
16. Set reset-synchronous PWM.
17. Enable channel 3 and 4 output with TOER.
18. Set MTU output with the PFC.
19. Operation is restarted by TSTR.
