9.2 Block description of pulse output port 0
Figure 9.2.1 shows the block diagram of pulse output port 0. Also, the pulse-output-port-0-relevant registers
In pulse output port 0 and three-phase waveform mode, the following registers are used in common: the
Note that, when not using pulse output port 0 and three-phase waveform mode, be sure to fix the waveform
