Motor Control Pwm Signals And Leds; Pwm Interface And Leds - Motorola 56F8323 User Manual

2.11 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
header, J5, and to the peripheral daughter card connector, J1, for easy use by the end user.
