11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in PWM Mode 1: Figure 11.106 shows an explanatory diagram of the
case where an error occurs in complementary PWM mode and operation is restarted in PWM
mode 1 after re-setting.

Recovery in PWM Mode 1
1 to 10 are the same as in figure 11.105.
11. Set PWM mode 1. (MTU output goes low.)
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC *B side is not initialized.)
13. Set MTU output with the PFC.
14. Operation is restarted by TSTR.
