Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
(16) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in Phase Counting Mode
Figure 11.152 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.
