Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(12) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in Reset-Synchronized PWM Mode
Figure 12.124 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.

Recovery in Reset-Synchronized PWM Mode
1 to 14 are the same as in figure 12.123.
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.
