Operation when Error Occurs during PWM Mode 1 Operation, and Operation is

Restarted in PWM Mode 1

Figure 12.132 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 12.131.

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 MTU2 output with the PFC.

14. Operation is restarted by TSTR.
