Section 9 Multi-Function Timer Pulse Unit 2 (MTU2)
Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in Phase Counting Mode: Figure 9.139 shows an explanatory diagram of the case where an error
occurs in PWM mode 2 and operation is restarted in phase counting mode after re-setting.
