2.9 Motor Control PWM Signals and LEDs
The 56F8323 has one PWM unit. This unit contains six PWM output signals, three Fault input
signals and three Phase Current sense inputs. The PWM signals are connected to a set of six
PWM LEDs via inverting buffers. The buffers are used to isolate and drive the processor’s PWM
outputs to the PWM LEDs. The PWM LEDs indicate the status of PWM signals; refer to
