Should not size be increased if psrc is moved down?
Example:
src = 0x0ffff; // pointed to the very end of a page
size = 2; // big enough to cross two pages
psrc = 0x0f000; // pointed to the start of the first page
size = 2; // does not include the second page anymore
second page is not checked
Or is this not a problem?
