In a checksum calculation of program and memory space, the checksum value calculated by program and the checksum value calculated with HTU8 do not match when the test data area (rewriting not possible area) of the program memory space segment) is included. Why?
When calculating the checksum of memory with program, if data in rewriting not possible area in the test data area are read, the actually written value is read. On the other hand, HTU8 handles the data in rewriting not possible area of the test data area as 0FFh. Therefore, the value is different from the checksum value of HTU8. When calculating the checksum with program, handle the rewriting not possible area data as 0FFh.
