Section 10 Multi-Function Timer Pulse Unit (MTU)
(16) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in Phase Counting Mode: Figure 10.100 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.
