Flash memory with range not definied

[maurom]

Hi,

im ready to Flash my S12 microcontroller through bdm interface and Hiwave.exe. I have saved flash memory in range 0x0e08000 to 0x0e7bfff, but inside it there is some block not defined.

I succeed to save range with (;A) append option in save command, but in the S19 file created there is some hole addresses, same of not defined block.

I need to change some bit in the range0x0e08000 to 0x0e7bfff of saved S19 file and then write changes.

If i try to flash this "holed" S19 file into microcontroller there is possibilitie some go wrong and i loss original memory?

Thanks a lot for any replies

Bye
