RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
23.2.18 Timer Output Control Registers 2 (TOCR2)
Note 1. Setting the TOCR1.TOCS bit to 1 makes this bit setting valid.
Note 2. If dead-time is not generated, the negative-phase output is always the exact inverse of the positive-phase output. In these
cases, only the OLSiP bits are valid (i = 1 to 3).
The TOCR2 registers control inversion of PWM output level in complementary PWM mode and reset-synchronized
PWM mode.
Note: The initial output value of negative-phase waveform changes to an active level after the dead time has passed since counting
starts.
