c - How to save values to PIC18? -

i store values pic18 retain values if power lost or unit reset. example of values save 4 digits, 0100.

any appreciated!

update: way go?

    unsigned char value;     unsigned char deedata = 0x25;     unsigned int  deeaddr = 0x04;      dataeeinit();     dataeeflags.val = 0;      dataeewrite(deedata,deeaddr);     value = dataeeread(deeaddr);     nop(); 

in mikroc_for_pic ide can use :

eeprom_write(_addres,char); char = eeprom_read(_addres);

note that: after write best if have delay 20 ms.
