4.6.1.18 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 from the data memory.
This option performs a similar task to the -mram and
-mrom options, but it cannot be used to add additional memory to that
available for the program.
