I want to calculate the checksum of the program memory space 64KB of segment 0 with the ML62Q1000 series program.
However, the entire program memory space of segment 0 cannot be read.
What should I do?
- The part of program memory space in segment 0 cannot be read as it is where it overlaps with the data memory space.
  Read segment 8 which is the mirror area of segment 0 instead.
  To read the program memory space of segment 0 through segment 8, declare the far pointer variable for data access and use it.
  For example, when reading segment 8 (0x80000-0x8FFFF) data in C language, declare the far pointer as shown below.
  
  uint8 __far *dat;
