Section 8 Multifunction Timer Pulse Unit (MTU)
(6) Operation when Error Occurs during Normal Mode Operation, and Operation is
Restarted in Reset-Synchronous PWM Mode
Figure 8.89 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 8.88.
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.
