• 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.

      #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".
