(14) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in PWM Mode 1: Figure 12.109 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.

Figure 12.109 Error Occurrence in PWM Mode 2, Recovery in PWM Mode 1
1 to 9 are the same as in figure 12.108.
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.
