Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(8) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in PWM Mode 1
Figure 12.132 shows an explanatory diagram of the case where an error occurs in PWM mode 1
and operation is restarted in PWM mode 1 after re-setting.

12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized.)
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
