16 Motor Control PWM (PWM)
Figure 16-18. Count-Up-Down, Dual Edge Symmetric Waveform, with Independent Modulation on PWMxA and
PWMxB — Active High
The duty modulation for PWMxA is set by A, active high and proportional to A.
The duty modulation for PWMxB is set by B, active high and proportional to B.
Outputs PWMxA and PWMxB can drive independent switches.
