Motorola MVME166IG/D2, MVME166D2 manual Debugger General Information

Debugger General Information

When using 166Bug, you operate out of either the debugger directory or the diagnostic directory. If you are in the debugger directory, the debugger prompt "166-Bug>" is displayed and you have all of the debugger commands at your disposal. If you are in the diagnostic directory, the diagnostic prompt

3"166-Diag>" is displayed and you have all of the diagnostic commands at your disposal as well as all of the debugger commands. You may switch between directories by using the Switch Directories (SD) command, or may examine the commands in the particular directory that you are currently in by using the Help (HE) command.

Because 166Bug is command-driven, it performs its various operations in response to user commands entered at the keyboard. When you enter a command, 166Bug executes the command and the prompt reappears. However, if you enter a command that causes execution of user target code (e.g., "GO"), then control may or may not return to 166Bug, depending on the outcome of the user program.

If you have used one or more of Motorola’s other debugging packages, you will find the CISC 166Bug very similar. Some effort has also been made to make the interactive commands more consistent. For example, delimiters between commands and arguments may now be commas or spaces interchangeably.
