The Paged Memory Management Unit functions-handler can be reached via the PMMU-Cookie, and is created by programs such as Outside or VRAM that can swap blocks of memory to and from a hard drive when insufficient RAM is available for a given task. These memory blocks will then lie in so-called 'virtual RAM' divided into 'pages' on the drive.
The handler can only be called in supervisor-mode, and works via a function number that is stored in data register d0. Possible return values will be found in this register as well. Other processor registers are not altered.
The following functions are available at present:
Important note: These functions only have meaning for a few programs in the region of system software, an have no place in user programs.
