Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) and Multi-Function Timer Pulse Unit 2S (MTU2S)
Operation when Error Occurs during: PWM Mode 2 Operation, and Operation is Restarted
in Phase Counting Mode Figure 10.152 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.
