MicroPower/Pascal Debugger

This document serves as the user's guide for the MicroPower/Pascal symbolic debugger, PASDBG. It details the debugger's features, covering host/target communication, command usage, symbolic debugging, and execution error management. The manual outlines the necessary hardware and software, the build procedures for debugging applications, and how to initiate and conclude a debugging session.

It provides a comprehensive overview of debugging techniques, including general-purpose commands for loading programs, resolving symbols and addresses, controlling program execution, examining and modifying data, and displaying data structures. Special attention is given to real-time debugging, with commands for monitoring process control blocks (PCBs), semaphores, ring buffers, packet queues, and handling exceptions. The guide also offers practical advice for dealing with real-time errors, critical sections, and race conditions. A complete alphabetical reference for all PASDBG commands, along with their syntax, parameters, and qualifiers, is included. The appendix further describes the communication protocols between the host debugger and the Debugger Service Module (DSM) on the target system.
