Ok i don´t need writecode to work over FFFF because 452 doesn´t has that memory size.

I am trying something already, by the way, can you help me with some info about the hex format? i need now to open an HEX file and send it through the serial port of my PC. When i open an HEX with notepad i get:

:10000000126AA5EF00F0ABB2AB98AB880C50006E53
:100010000D50016E026A036A000000D004009EBA0F
:1000200013D0FF0E0226D8A00326D8A00026D8A001
:100030000126D8A0A2EF00F00248033CEDD7FA0E4B
:10004000026E000E036EEAD7AE50D880A2EF00F029
:1000500004009EA8FDD7AD6ED880A2EF00F0076E19
:100060008490809A809A9690929A929AF00E941622
:10007000075012B222D03A0E016E980E93EC00F0A7
:10008000330E066E30D8130E016E880E93EC00F01E
:100090002AD8640E92EC00F026D8640E92EC00F0A0
:1000A000220E066E20D8280E07D80C0E05D8060E94
:1000B00003D81282075001D01280066E12A00BD016
:1000C000809A03080EE30DD8070E016ED00E93EC54
:1000D00000F0D88012001280FE08D8B4A2EF00F021
:1000E000808A063A12A012908480F00E8216065082

this doesn´t look nice at all, and i dont find the match with for example

0000- 6a12 efa5 f000 b2ab 98ab 88ab 500c 6e00
0008- 500d 6e01 6a02 6a03 0000 d000 0004 ba9e
0010- d013 0eff 2602 a0d8 2603 a0d8 2600 a0d8
0018- 2601 a0d8 efa2 f000 4802 3c03 d7ed 0efa

Is it correct for me to think that writing this last words to the appropiate addreses will get the uC correctly programmed?

:10 0000 00 126A A5EF 00F0 ABB2 AB98 AB88 0C50 006E 53
10 = record type
0000 = start address
00 = number of bytes in record, 00=16??? Not 100% sure on this
126A = data, look below at your 2nd chunk of data sent...look familiar?

0000- 6a12 efa5 f000 b2ab 98ab 88ab 500c 6e00

The 1st file you sent is an actual INTEL HEX file, which is a different format than...
The 2nd file chunk you sent...which is actual data.

Google 'INTEL HEX record', you should find all the info you need somewhere out there...
