11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during Phase Counting Mode Operation, and Operation is
Restarted in PWM Mode 2: Figure 11.103 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.

1 to 9 are the same as in figure 11.101.
10. Set PWM mode 2.
11. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized.)
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.
