C flag is clear if the range is OK, else set |
The purpose of this call is to check that a range of addresses are in logical RAM.
SWI checks the address range between R0 and R1-1 to see if the specified range lies in logical RAM and has a mapping into physical RAM.
This call does not check that the memory actually exists, only that it ought to exist. If you have used OS_SetMemMapEntries, then this call will not work as expected.
