C24x PWM
3-17
Symmetric. The following illustration shows the difference between the two
types of waveforms.
Enable PWM#/PWM# — Check to select the PWM pairs to activate
Pulse width source — Source from which the pulse width is obtained. Select
Specify via dialog to enter the value in Pulse width or select Input port to
use a value from the input port.
Pulse width — Width of the pulse in clock cycles. The default is for the first
PWM in a pair to be triggered Active high and for the second PWM to be
triggered Active low. You can change the PWM control logic by selecting
