Abstract
An in-system debugging (ISD) capability is incorporated into a production microcontroller. The ISD capability is incorporated without the costly addition of any extra pins to read out the data for debugging by using the oscillator pins of the production microcontroller to read out the data. Building such an ISD capability into the microcontroller, enables debugging to be performed on the actual production board (instead of a special debug board) having the actual production microcontroller (instead of a bond-out microcontroller). This allows designers to debug programming using the actual production system instead of an emulation system.
