Section 15 14-Bit PWM
Section 15 14-Bit PWM
The 14-bit PWM is a pulse division type PWM that can be used for electronic tuner control, etc.
Figure 15.1 shows a block diagram of the 14-bit PWM.
15.1 Features
• Choice of two conversion periods
A conversion period of 32768/φ with a minimum modulation width of 2/φ, or a conversion
period of 16384/φ with a minimum modulation width of 1/φ, can be selected.
• Pulse division method for less ripple
