DEBUG MONITOR COMMANDS
M68CPU32BUG/D REV 1 3-59
SD Switch Directories SD
3.29 SWITCH DIRECTORIES
SD
Use the SD command to toggle between the debugger directory and the diagnostic directory.
Use the HE (Help) command to list the current directory commands.
Directory structure allows access to the debugger commands from either directory but the
diagnostic commands are only available from the diagnostic directory.
EXAMPLES
CPU32Bug>SD<CR>
CPU32Diag>
The user has changed from the debugger
directory to the diagnostic directory, as can
be seen by the ’’CPU32Diag>’’ prompt
CPU32Diag>SD<CR>
CPU32Bug>
The user is now back in the debugger
directory.
