Hello,

I need information about non-volatile memory.

Firstly, this is one part of my program. It'll be easier to explain my 
problem :

if (SAU_A == high & SAN_A == high) then
   n = 1
   repeat
   if (n==1 & SAD_A == high) then
      repeat
      first = adc_read(0)               <---<---<---
      until(SAD_A == low)
      n = n+1
   end if
   fd = first - ramin
   fu = first + ramax
   until(SAU_A == low)
end if


So when I push on the buttons (SAN_O, SAU_O and SAD_O), it allow to read 
the analog input and save the value into variable first (var dword first) 
(see line with the arrows). 
The problem is that when I turn off the micro-controller (remove the 
battery) it looses the variable first. I would like to keep in memory the 
variable even if I turn off the micro-controller. 
Do you know how can I put the value in the eeprom or something equivalent ?


Kind regards,

Sébastien
