Vectors numbered 12 to 23 and 48 to 63 are reserved for future extensions. No device should be assigned there.
Note: regarding the MFP, a circuit generating a large portion of interrupts in the ST, it uses, of course, user interrupt vectors. Indeed, when talking about users here, it is not about you, but the people who use the 68000 to build their machines, that is to say people from ATARI, COMMODORE or APPLE!
