Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(23) Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Complementary PWM Mode
Figure 12.147 shows an explanatory diagram of the case where an error occurs in complementary
PWM mode and operation is restarted in complementary PWM mode after re-setting (when
operation is restarted using the cycle and duty settings at the time the counter was stopped).
