RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
23.3.7 Reset-Synchronized PWM Mode
In the reset-synchronized PWM mode, six phases of positive and negative PWM waveforms that share a common wave
transition point can be output by combining MTU3 and MTU4.
When set for reset-synchronized PWM mode, the MTIOC3B, MTIOC3D, MTIOC4A, MTIOC4C, MTIOC4B, and
MTIOC4D pins function as PWM output pins and the MTU3.TCNT counter functions as an up-counter.
Table 23.49 lists the PWM output pins. Table 23.50 lists the settings of the registers.
