How can I configure the debugger to not erase data flash in 10.5?

In Codewarrior 10.5 for DSC (568367) I want to disable download to data the data flash (range 04000-07FFF). In the classic Codewarrior you could just comment out the line in the .cfg file. Can you change the .mem file to prevent the debugger from erasing this section? I tried to change the permission to "Read" but it still erased it.

// Memory Map:

// ----------------------------------------------------------------------

// <memory address rage> <access size> <permission>

range p:0x00000000 p:0x0003FFFF 2 ReadWrite // FLASH

range p:0x00040000 p:0x00043FFF 2 ReadWrite // FLASH

reserved p:0x00044000 p:0x0004F7FF

range p:0x0004F800 p:0x0004FFFF 2 ReadWrite // RAM

reserved p:0x00050000 p:0x001FFFFF

range x:0x00000000 x:0x00003FFF 2 ReadWrite // RAM

range x:0x00004000 x:0x00007FFF 2 Read // FLASH

reserved x:0x00008000 x:0x0000EFFF

// x:0x0000F000 x:0x0000FFFF 2 ReadWrite // Memory Mapped Registers

reserved x:0x00010000 x:0x00FFFEFF

// x:0x00FFFF00 x:0x00FFFFFF 2 ReadWrite // Memory Mapped Registers

Hello,

if you are using P&E Multilink, then you can preserve memory ranges from beeing erased:

Hi Erich,

Yes I am using a P&E Multilink. The link you gave was helpful but I do not see the same "Advanced Options" page that is shown in your link. I do not see a way to define memory for preservation. I see the followoing on the Advanced options page. Is this feature hidden somewhere else? I really appreciate your help.
