(26) Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and

Operation is Restarted in PWM Mode 1: Figure 12.122 shows an explanatory diagram of the

case where an error occurs in reset-synchronous PWM mode and operation is restarted in PWM

mode 1 after re-setting.

Recovery in PWM Mode 1

1 to 10 are the same as in figure 12.121.

11. Set PWM mode 1. (MTU positive phase output is low, and negative phase output is high.)

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

13.Set MTU output with the PFC.

14.Operation is restarted by TSTR.
