11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in PWM Mode 2: Figure 11.99 shows an explanatory diagram of the case where an error occurs
in PWM mode 2 and operation is restarted in PWM mode 2 after re-setting.

1 to 9 are the same as in figure 11.97.
10. Not necessary when restarting in 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.
