Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) and Multi-Function Timer Pulse Unit 2S (MTU2S)
Operation when Error Occurs during PWM Mode 1 Operation, and Operation is Restarted
in Reset-Synchronized PWM Mode: Figure 10.148 shows an explanatory diagram of the case
where an error occurs in PWM mode 1 and operation is restarted in reset-synchronized PWM
mode after re-setting.

1 to 14 are the same as in figure 10.147.
15. Select the reset-synchronized PWM output level and cyclic output enabling/disabling with
TOCR.
16. Set reset-synchronized PWM.
17. Enable channel 3 and 4 output with TOER.
18. Set MTU2 output with the PFC.
19. Operation is restarted by TSTR.
