Thread: Register variable

I have an problem with my code, it has to read the registers of the microcontroller and then store it in ddr

Code:

char leesOutput( char nummer )
{
  unsigned char ddr[4];
  char output = 0;
  /*DDR Variable with Registers*/
  switch( nummer )
  {
  case 1: // Out 1
    output = ( ddr[ 0 ] >> 0 ) & 0x01;
    break;
  case 2: // Out 2
    output = ( ddr[ 0 ] >> 1 ) & 0x01;
    break;
  case 3: // Out 3
    output = ( ddr[ 0 ] >> 2 ) & 0x01;
    break;
  case 4: // Out 4
    output = ( ddr[ 0 ] >> 3 ) & 0x01;
    break;
  case 5: // Out 5
    output = ( ddr[ 0 ] >> 4 ) & 0x01;
    break;
  case 6: // Out 6
    output = ( ddr[ 0 ] >> 5 ) & 0x01;
    break;
  case 7: // Out 7
    output = ( ddr[ 0 ] >> 6 ) & 0x01;
    break;
  case 8: // Out 8
    output = ( ddr[ 0 ] >> 7 ) & 0x01;
    break;
  case 9: // Out 9
    output = ( ddr[ 2 ] >> 7 ) & 0x01;
    break;
  case 10: // Out 10
    output = ( ddr[ 2 ] >> 6 ) & 0x01;
    break;
  case 11: // Out 11
    output = ( ddr[ 2 ] >> 5 ) & 0x01;
    break;
  case 12: // Out 12
    output = ( ddr[ 2 ] >> 4 ) & 0x01;
    break;
  }
  return output;
}

The place of the code is indicated with bold lettertype. I have been looking in the datasheet of the Microcontroller and I couldn't find anything. Microcontroller = Fujitsu MB90495 Family
