Read-Only Author steven hsu Posted 20-Sep-2004 04:04 GMT Toolset C251	change region address of the external data memory steven hsu I want to change the DPXL from 01h (default) to FFh(the region address of the code memory) So I can access(R/W) the code memory by the inst(MOVX) When I use the simulator of the C251 eval version, there's error message while I access in this way. the message is "error65: access violation at 0xFF0300: no 'write' permission" Is this a constraint? or I can change some setting to solve this issue. Thans for the great help. :)

You can use the MAP command and change the attribute of the region 0xFF0000 - 0xFFFFFF to READ WRITE EXEC. For more information refer to the MAP command in the on-line help file Keil\C251\Hlp\Dbg251.CHM.
