NOTES:
PWM mode is to output a PWM waveform. 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, any of PWM mode, other modes or functions can be selected every 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 14.63 shows the Block Diagram of PWM Mode, Table 14.27 lists the PWM Mode Specifications.
Figures 14.64 to 14.73 show the Registers Associated with PWM Mode and Figures 14.74 to 14.75 show the
Operations of PWM Mode.
