Your program contains a lot of code that is not required to show your problem.
Also, you will get much better responses when you post the output that you get and the data that you expected. Now you leave it to us to read your mind to figure out what is wrong.
Just something I noticed: | Code: | .................... write_program_memory(0xaf00,write_data,8);
035C: MOV #AF00,W0
035E: MOV #0,W1
0360: MOV #1062,W2
0362: MOV #8,W3
0364: CALL 22C
....................
.................... read_program_memory(CK_USER_PAGE,read_data,8);
0368: MOV #A000,W0 |
You are writing to address 0xAF00 but reading from 0xA000. No wonder you get different results. |

| As one other tiny comment. Be aware of just how large the page size is on this chip. A write to 0xAF00, will not trigger an erase (not on a page boundary). Also, you need to ensure the page is 'reserved' (no code being put there), so have a #ORG with start and end addresses, and a 'dummy' function containing nothing, to ensure that the compiler will not put code into the addresses. |

There was a problem in the compiler 5.021.
In 5.023 write_program_memory works. |

Found another problem.
After erase_program_memory, write_program_memory not work.
So also does not work if write_program_memory writing from start of the page. |
