i'm trying to write to the internal EEPROM of the 16c84. the problem is that i can read from it ( pre-programmed values) but i can't write to it. i'm using te following (standard)program to read and write the 16c84. can someone tell me what i'm doing wrong ????

#include <16C84.h>

#define Enable_EE_WR       EECON1.WREN = 1
#define Disable_EE_WR      EECON1.WREN = 0
#define EEProm_Rd          EECON1.RD   = 1
#define EEProm_Writing     EECON1.WR

int Read_EEProm(registerw addr);
void Write_EEProm(registerx addr, registerw data);

void main()
{
unsigned int addr, data;

data = 0x18; // Data to be written/read
addr = 0x00; // Address to write to

//-------------- EEPROM WRITE ----------------
Write_EEProm(addr,data);
while(EEProm_Writing);

//--------------- EEPROM READ -----------------
data = Read_EEProm(addr);

TRISB = 0x00;
PORTB = data;
while(1);
}

int Read_EEProm(registerw addr)
{
EEADR = addr;
EEProm_Rd;
return(EEDATA);
}

void Write_EEProm(registerx addr, registerw data)
{
Enable_EE_WR;
EEDATA = data;
EEADR = addr;
