In PWM mode, a PWM waveform is output. Up to 3 PWM waveforms with the same period can be output by timer
RDi (i = 0 or 1). Also, up to 6 PWM waveforms with the same period can be output by synchronizing timer RD0
and timer RD1. 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 20.14 shows a Block Diagram of PWM Mode, and Table 20.9 lists the PWM Mode Specifications. Figures
20.15 and 20.16 show the Operations of PWM Mode.
