11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in PWM Mode 1: Figure 11.98 shows an explanatory diagram of the case where an error occurs
in PWM mode 2 and operation is restarted in PWM mode 1 after re-setting.

1 to 9 are the same as in figure 11.97.
10. Set PWM mode 1.
11. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized.)
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.
