How do I make a reference to a value stored in Segment 1 with C language?
- When referring to the content of program space on Segment 1, use "__far pointer" as shown below.
  
  Example
  #define SEG_ADDRESS_BASE 0x10000 //Define the base address of Segment 1
  
  int main( void )
  {
  
  unsigned char buffer[8];
  unsigned char i;
  
  for(i = 0; i < 8; i++){ //Read 8-byte from address 0000H in Segment 1
  buffer[i] = *((unsigned char __far*)SEG_ADDRESS_BASE + i);
  }
  
  }
  
  For __far pointer, refer to "1.4 NEAR/FAR" in "CCU8 Programming Guide".
