M-Station Baseboard
8. USING OPTMST TO SET FLASH PROGRAMMING OPTIONS
When the M-Station is used to flash program an NEC Electronics 78K0 or 78K0S microcontroller, the
details of the algorithms used to program the device are contained in a parameter file, with the
extension .PRC, which is read in by the FP4MST program.
There are options in flash programming that are not specified by the .PRC file, but instead must be set
by you. These options are stored in the system registry and are available to the FP4MST program
when it is executed. The OPTMST program is used to set the state of these options in the registry:
•
Source and frequency of the main clock for the microcontroller
•
Communication port and speed for flash programming
•
V
DD
and V
PP
voltage settings, for checking against selected .PRC file
•
Additional timing parameters for adjustment of algorithms
•
Whether to automatically load the .PRC file, or to prompt the user for it
Usually the OPTMST program needs to be run only when first configuring the M-Station hardware and
software for flash programming. After the initial settings are made, the FP4MST program will run
without adjustment of these settings.
