(9) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in PWM Mode 2: Figure 8.57 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.

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.
