Operation when Error Occurs during Phase Counting Mode Operation, and Operation is
Restarted in PWM Mode 1: Figure 9.141 shows an explanatory diagram of the case where an
error occurs in phase counting mode and operation is restarted in PWM mode 1 after re-setting.
1 to 9 are the same as in figure 9.140.
10. Set PWM mode 1.
11. Initialize the pins with TIOR. (In PWM mode 1, the TIOC *B side is not initialized.)
12. Set MTU2 output with the PFC.
13. Operation is restarted by TSTR.
