10. PWM UNIT
is ideal for the actuator control signal for motors, etc.
10.1 FEATURES
10.2 PWM UNIT CONFIGURATION
The PWM register is not affected by reset input.
The V55PI is provided with an 8-bit precision PWM (pulse width modulation) signal output function.
PWM output can be used as a digital-to-analog conversion output by connecting a low-pass filter, etc., externally. This
The PWM unit offers the following features:
The configuration of the PWM unit is shown in Figure 10-1.
The PWM unit consists of the PWM register (PWM) and PWM control register (PWMC), and an 8-bit counter.
The PWM register controls the pulse width (duty) in the PWM output mode. The 8–bit counter is set to 00H by reset input.
