Prototype

void Eeprom_Write(char address, char data);

Description Writes data to the specified address. Parameter address is of byte type, which means it

can address only 256 locations. For PIC18 micros with more EEPROM data locations, it

is programmer’s responsibility to set SFR EEADRH register appropriately.

Be aware that all interrupts will be disabled during execution of EEPROM_Write rou-

tine (GIE bit of INTCON register will be cleared). Routine will set this bit on exit.

Requires Requires EEPROM module.

Ensure minimum 20ms delay between successive use of routines

Eeprom_Write and

Eeprom_Read. Although PIC will write the correct value, Eeprom_Read might return

an undefined result.

Example

Eeprom_Write(0x32);

Eeprom_Read

unsigned short i = 0, j = 0;

void main() {

PORTB = 0;

TRISB = 0;

j = 4;

for (i = 0; i < 20u; i++)

Eeprom_Write(i, j++);

for (i = 0; i < 20u; i++) {

PORTB = Eeprom_Read(i);

Delay_ms(500);

}

}//~!
