Operation when Error Occurs during PWM Mode 1 Operation, and Operation is Restarted
in PWM Mode 1: Figure 10.92 shows an explanatory diagram of the case where an error occurs
in PWM mode 1 and operation is restarted in PWM mode 1 after re-setting.

1 to 10 are the same as in Figure 10.91.
11. Not necessary when restarting in PWM mode 1.
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.
