In PWM mode, a PWM waveform is output. Up to 3 PWM waveforms with the same period can be output by 1
channel. Also, up to 6 PWM waveforms with the same period can be output by synchronizing channels 0 and 1.
Since this mode functions by a combination of the TRDIOji (i = 0 or 1, j = B, C, or D) pin and TRDGRji
register, the PWM mode, or any other mode or function, can be selected for each individual pin. (However,
since the TRDGRAi register is used when using any pin for PWM mode, the TRDGRAi register cannot be used
for other modes.)
Figure 14.62 shows a Block Diagram of PWM Mode, and Table 14.27 lists the PWM Mode Specifications.
Figures 14.63 to 14.72 show the Registers Associated with PWM Mode, and Figures 14.73 and 14.74 show
Operating Examples of PWM Mode.
