Pcnec must be invoked with root permissions!
Typing pcnec -h the list of available options will be displayed.
For example, -n option specify that blank check control is not required (this speed-up
programming for the high-volume stage).
Another important option is -c clock which permit
to set the target oscillator clock in KHz: this is needed because erase/program feature is performed by
the Nec microcontroller built-in firmware, which need several instruction-cycles to be execute, so
all timings are related to the clock applied to the microcontroller.
To speed up microcontroller programming, higher clock is preferred. Default is 8MHz, but if you
are using 7.372800 MHz clock, you must specify -c 7372 option.
The correct syntax is pcnec [options] <hexfile>, for example
pcnec -c 7372 devel/osd.hex where osd.hex is an Intel-Hex file.
3.1 General Usage
The program should be called with several optional command line parameters, as shown
calling pcnec -h.
