The PMON Monitor

The PMON Monitor provides a powerful set of assembly-level debugging commands, as well as a mechanism to permit it to be used as the execution vehicle for source-level debuggers.

This section provides information about the internals of PMON. This can help you if you plan to modify PMON, or if you are using it in a non-standard configuration.

• How Breakpoints Work. This describes what PMON does when you set a breakpoint in your code.

• How Printf Works. This describes the call tree that is invoked whenever any of the stdio functions are used to print information to the screen.

• PMON Initialization. This provides a detailed description of the code executed between the reset vector, and the first message that is printed to the screen.

Customizing PMON

This section contains information about customizing PMON to make it suitable for your own application or hardware platform.

• Adding a Command. You can add your own commands to perform application-specific operations for testing and debug purposes.
