Problem with digital I/O on GP5 of 12F675. GO5 is not responding as input or output.

Code: 
int x =0, y = 0, cnt = 0;
void main() 
{
CMCON=0x07;
ANSEL=0x00;
OSCCAL = 0xFF;
TRISIO=0b00011100;;
GPIO=0x00;
WPU = 0x00;
while(1)

{
   while(GP2_bit == 1)
  {
   x = x^y;
   EEPROM_Write(0x01,x);
   Delay_ms(500);
   break;
  }
  EEPROM_Read(0x01);
  if(x == 1)// Automatic service !!!
  {
   cnt++;
   while(cnt >= 50)
   {
    GP0_bit = ~GP0_bit;
    cnt = 0;
    Delay_ms(10);
    break;
   }
   if(GP4_bit == 1)
   {
   GP5_bit = 0; // Relay will on if LDR  senses no light;
   Delay_ms(20);
   }
   else
   {
    GP5_bit = 1;
    Delay_ms(20);
   }
  }
  else // Manual service !!!
  {
   y = 1;
   GP0_bit = 1;
   Delay_ms(200);
   GP5_bit = 1;
  }

}

}
 

Your configuration code doesn't work? I don't understand--you have to make sure you are disabling the CLKOUT function on the pin that serves as GP5.
 

In mikroC, the configuration settings must be done here: Project > Edit Project (Cntrl + Shift + E). Not in code.

Hope this helps.
Tahmid.
