(2) Operation when Error Occurs during Normal Mode Operation, and Operation is

Restarted in PWM Mode 1

Figure 18.86 shows an explanatory diagram of the case where an error occurs in normal mode and
operation is restarted in PWM mode 1 after re-setting.

1 to 10 are the same as in figure 18.85.

11. Set PWM mode 1.

12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized. If

initialization is required, initialize in normal mode, then switch to PWM mode 1.)

13. Set MTU output with the PFC.

14. Operation is restarted by TSTR.
