Applications should use the 0x80003F00 - 0x81330000 area for executable code and data loaded as part of their ELF/DOL, while loaders should use from 0x81330000 onwards. Applications can use the loader area and MEM2 as data work space once they are running, but they should restrict the sections contained in the DOL or ELF to the executable area only, since MEM2 is reserved as work area for the loader at that time. To preserve "return to loader" functionality, applications should never use the 0x80001800-0x80003000 area.

Applications should use the 0x80003F00 - 0x81330000 area for executable code and data loaded as part of their ELF/DOL, while loaders should use from 0x81330000 onwards. Applications can use the loader area and MEM2 as data work space once they are running, but they should restrict the sections contained in the DOL or ELF to the executable area only, since MEM2 is reserved as work area for the loader at that time. To preserve "return to loader" functionality, applications should never use the 0x80001800-0x80003000 area.
