This LSI has an on-chip 14-bit pulse-width modulator (PWM) timer with four output channels. It
can be connected to an external low-pass filter to operate as a 14-bit D/A converter.

• Division of pulse into multiple base cycles to reduce ripple
• Eight resolution settings
• Two base cycle settings
• Sixteen operation clocks (by combination of eight resolution settings and two base cycle
Figure 10.1 shows a block diagram of the PWM (D/A) module.

The resolution can be set to 1, 2, 64, 128, 256, 1024, 4096, or 16384 system clock cycles.
The base cycle can be set equal to T × 64 or T × 256, where T is the resolution.
