Operation when Error Occurs during Phase Counting Mode Operation, and Operation is
Restarted in PWM Mode 2: Figure 9.142 shows an explanatory diagram of the case where an
error occurs in phase counting mode and operation is restarted in PWM mode 2 after re-setting.
MTU2 module output
1 to 9 are the same as in figure 9.140.
10. Set PWM mode 2.
11. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized.)
12. Set MTU2 output with the PFC.
13. Operation is restarted by TSTR.
