Hi!
In the SIC-Technical registers paper I read that the write protection bit (bit 7) needs to read zero to be on, and reads one to be off.
But my question is now:
When I remove the write protection; how to write something to the flash chip?
The last two lines of the SIC-Register document are not clear to me.
A short example would help.
Another question:
Does the FLASHchip works like an Eprom, and needs data to be erased before it can be re-programmed?( I know in Eprom when bits are once set, they need to be switched back to zero before they can be programmed again)
And is it possible to erase just a smaller part of the chip.
If someone could explain me how to do that too... I would be very thankful.
Ofcourse I would appreciate a suggestion in the right direction too...
