NEC PG-FP4 User Manual page 17

The graphical user interface (GUI) of the PG-FP4 supports the device commands necessary for downloading and
uploading user programs, setting parameters necessary for writing the device, setting and selecting a writing
environment by the user, changing the user program downloaded to the PG-FP4, and calculating and rewriting the
memory checksum.
The parameters necessary for writing the device are saved to a parameter file (PRM file) and the setting of the
user's writing environment is saved to a customized setup file (SET file). These files are downloaded to the PG-FP4
and stored in the internal EEPROM, so that the downloaded data can be used even in the standalone mode. The GUI
software is executed using the parameters that have been set last. Changed settings are saved to an INI file.
Communication between the GUI software and the PG-FP4 is recorded in an ASCII file.
The internal memory of the PG-FP4 is configured as a 2 MB flash memory and holds the user program that is
written to the target device. This memory's area (progarea) can be divided into two 1 MB memory areas. Therefore,
the PG-FP4 can download two different user programs and select either of them as the valid user program.
