(14) Operation when Error Occurs during Phase Counting Mode Operation, and Operation

is Restarted in PWM Mode 1: Figure 10.73 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 10.72.

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.
