RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
Note: The initial output value of negative-phase waveform changes to an active level after the dead time has passed since counting
starts.
Figure 23.2 shows an example of output in complementary PWM mode (one phase) when OLSN = 1 and OLSP = 1.
