I should have stated that it was in ANSI C.

Thank you both.

Without knowing anything about this NAND FLASH controller you have, it
is impossible to answer your question.

A MMC card is typically a NAND-FLASH with a SPI interface; a search
for NAND FLASH SPI would undoubtedly be helpful.

Google; it's not just for mail anymore!

Sorry never used any of them. Choose the one that suits your needs and
you can get.

I think you will find that's in the abs max section of the data
sheet.  Microchip (I remember that's who you are using) has the
following note in that section "Exposure to maximum rating conditions
for extended periods may affect device reliability."   These are
stress ratings not operating ratings.  That is true for all
manufacturers AFAIK although some are not as explicit about it.

In other words don't do that.

For driving a load a much prefer using something like a bss123 to do
the actual drive and have the micro turn it on/off.  That also
isolates you from the load voltage to some extent.

That's the problem I have with Visual Basic.  I can never decide if
I'm still 10 years old and wiriting in basic, or all grown up and
writing in C.  Both mindsets sort of work, but neither one really fits
that language.  So I have these  terrible mixes of old basic
manipulations next to examples of VB doing a bad job of pretending to
be C.

I'm in trouble,
do you think that could be possible to program the FPGA from ethernet
for this board ?
Thanks,
