Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in PWM Mode 1: Figure 9.125 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.
MTU2 module output
1 to 10 are the same as in figure 9.124.
11. Set PWM mode 1.
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized. If
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
