Philips 8xC552/8xC554 PWM Example Program

This example program shows how to configure and use the Pulse Width Modulator of the following microcontrollers:

• Philips 80C552
• Philips 80C554
• Philips 83/87C552
• Philips 83/87C554
• Philips 83/87C557E4
• Philips 83/87C557E8

After configuring the PWM, the program runs a continuous loop to allow the PWM to constantly run in the background.

A debug script (DEBUG.INI) includes a debugger function that outputs a text representation of the PWM output pins. As the program runs the changes in voltage are displayed as a strip chart recorder.
