11.1
The H8/3644 Group is provided with a 14-bit PWM (pulse width modulator) on-chip, which can
be used as a D/A converter by connecting a low-pass filter.
11.1.1
Features of the 14-bit PWM are as follows.
11.1.2
Figure 11.1 shows a block diagram of the 14-bit PWM.
Choice of two conversion periods
A conversion period of 32,768/ , with a minimum modulation width of 2/ or a conversion
period of 16,384/ , with a minimum modulation width of 1/ can be chosen.
