6.5.28 Pulse Width Modulator (PWM)
Short Description:
The Pulse Width Modulator (PWM) instruction modulates the analog input value Ax to a pulsed digital output
signal. The pulse width is proportional to the analog value Ax.
connection
Description
EN
A positive edge (0 to 1 transition) at
input En enables the PWM function
block.
Input Ax
Analog signal to be modulated to a
pulsed digital output signal.
