2.11 Motor Control PWM Signals and LEDs
The DSP56F801 has one dedicated PWM unit. The PWM unit’s lines are connected to the
UNI-3 interface connector and to a set of six PWM LEDs via inverting buffers. The
inverting buffers are used to isolate and drive the DSP’s PWM’s outputs to the PWM
LEDs. The PWM LEDs indicate the status of PWM’s signals, as shown in
.
The PWM signals are routed to a header, J1, and are available for use by the end user.
