 		 #108209 - Somehow it would be nice, albeit seeming
Responding to: ???'s previous message

You do realise that the 8051 has no instruction to write to CODE space, don't you?
Therefore, to write to your FLASH, you have to have some cunning scheme to make it appear in XDATA space...

the reply:
My idea is to have a PC software to be used only during programming cycles. Thus, our design which consists in a 51 micro and external flash could be programmed in-system.

we have a perfect expression for that in Danish
Godag mand oekseskaft
hello man, axhandle
based on an old story about a deaf person

Somehow it would be nice, albeit seemingly impossible, if all responses had, at least a bit of, relevance to the questions.
