NOTE

You simply click on a module in the list to select and/or use Select All/
Unselect All buttons to adjust your selection. But selecting and unselecting are
not automatic from the command line. Before you use the command line to
perform any operation on a module, you must use the SELECT command to
select the module. Also see the FLASH SELECT and FLASH UNSELECT
commands in this chapter.

MCU Speed Information

The displayed MCU speed is the device bus speed/clock sensed by the Flash programmer;
same value as the one returned by the FLASH command.

CAUTION

A non-relevant displayed speed is symptomatic of a Flash programmer
diagnostic problem. If this occurs, close the dialog box, check the
hardware, and reset the connection.

Configuration: FPP File Loading

When the dialog box is open, the NVMC utility loads the .FPP configuration file
according to this algorithm:

1. The utility reads the NV_PARAMETER_FILE entry from the connection-specific

section of the project.ini file. [HCS08 Open Source BDM] is a connection-
specific section.

Example:

[HCS08 Open Source BDM]

NV_PARAMETER_FILE=C:\MYINSTALL\PROG\FPP\mcu1027.fpp

2. If the utility retrieves a valid .FPP file name, it loads the file.

3. If the utility cannot find a valid .FPP file name, it displays an appropriate error

message.

4. If the utility does not find an entry, or if it finds an empty entry, the utility

automatically checks the Auto select according to MCUID: checkbox. Then the
utility loads the parameter file from the \FPP subdirectory of the CodeWarrior IDE
installation, according to the MCUID.

5. If the utility finds a file that has the wrong format, it displays an appropriate error

message.

6. The utility always displays the MCUID, if the Id is available from the connection.
