# README.TXT

This project is a generic base for a HC12 ANSI-C project debugged with a P&E Cable12 .
 
Project layout:
===============

Folders used:

- Sources: Will contain your sources. For the moment, it contains an empty 'main.c' as a base.
  -------
- Debugger Cmd Files: Here you can place your own specific debugger command files.
  ------------------
- Startup Code: Contains the startup code of the application. You may adapt it
  ------------  to your own needs, but in such a case make sure that you create a local copy.

- Prm: Contains the linker parameter file used for linking (.prm)
  ---  and a Batch Burner command file (usual extension is .bbl, see \docu\common\manual\Manual Burner.pdf )
       Note that the file used for the linker
       is specified in the Linker Preference Panel itself (<ALT-F7>

- Libs: Contains the ANSI library to be linked with.
  ----
- Debugger Project File: This .ini file is passed to the debugger/simulator
  ---------------------  as configuration file. It contains various target interface settings, and path
                         information as well. This file can also be edited from the simulator/debugger e.g. using
                         File->Configuration in the simulator/debugger.

- Debugger Cmd Files: these files contain commands to be played at specific stages of the process.
  ------------------
	-startup.cmd:  This command file is executed to set up the target system just 
				   after the connection has been established.
	-reset.cmd:    This command file is executed after a user enforce reset has been 
				   performed (the Reset button, menu entry or command line command has been used).
	-preload.cmd:  This command file is executed before an application (code or symbols) 
	               is loaded in the debugger.
	-postload.cmd: This command file is executed after an application (code or symbols) 
	               has been loaded in the debugger.
    -vppon.cmd:    This command file is executed before Non Volatile Memory is erased 
                   or programmed using the NVMC dialog or the corresponding debugger command.
    -vppoff.cmd:   The Vppoff command file is executed after Non Volatile Memory has
                   been erased or programmed using the NVMC dialog or the corresponding debugger command.

Build Targets:
==============

This project contains following build targets :
- Ram Application : Build settings are suitable for an application located in Ram.
- Flash Application : For code located in Flash.
- Banked Flash : For code located in banked Flash.

Compiler options: 
=================
The Compiler option -ol0 has been set up to disable some compiler optimizations
in order to be able to see all the local variables in the debugger Data component.


Hardware Notes:
===============
WARNING: The onchip flash memory will be erased and written each time you 
perform a load. Please check "preload.cmd" and "postload.cmd" command files
execution to enable/disable this process. The execution of these command files
is monitored with the ICD12 | Command Files dialog.

WARNING: In order to Flash, please make sure the correct programming voltage is 
supplied to the microcontroller and the correct MCUID has been used.
