Only available information comes from netbsd and linux sources:
Something to do with interrupts but are they input or output or both? Mainboard inputs? Does writing cause interrupts? What?
Does the file src/sys/arch/amigappc/amigappc/pic_amiga.c in the NetBSD source give any clues?
Also src/sys/arch/amigappc/amigappc/locore.S
and maybe src/sys/arch/amigappc/amigappc/machdep.c
