3.6.1.13 Reserve Option
The
-mreserve=ranges option allows you
to reserve memory normally used by the program. This option has the general
form:-mreserve=space@start:endwhere
space can be either of ram or
rom, denoting the data and program memory spaces, respectively; and
start and end are
addresses, denoting the range to be excluded. For example,
-mreserve=ram@0x100:0x101 will reserve two bytes starting at address
100h in the data memory; or -mreserve=rom@0x1000:0x11FF will reserve
addresses 0x1000 to 0x11FF in program memory.
