Section 9 Multi-Function Timer Pulse Unit 2 (MTU2)
Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in PWM Mode 2: Figure 9.138 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.

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.
