11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in Phase Counting Mode: Figure 11.100 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.
