Abstract
A debug module ( ) is provided which allows a developer to capture three types of debug information. The three types of debug information are: change-of-flow addresses, CPU data, and current instruction addresses. The debug information is captured in an on-chip debug FIFO memory ( ) during program development. The debug information is provided to an external host via a serial communication interface ( ) for post-processing and analysis. Storing and retrieving program information in this way is useful in microcontrollers that do not provide external access to address and data bus signals.
