VMEbus IACK (1-7) Registers
Reading these registers causes an interrupt acknowledge cycle on the VMEbus. A 32-bit read
of these registers causes a 32-bit IACK cycle on the VMEbus. A 16-bit read of these registers
causes a 16-bit IACK cycle on the VMEbus. An 8-bit read of these registers causes an 8-bit
IACK cycle on the VMEbus. Since most VMEbus interrupters support 8-bit IACK cycles,
byte reads from offset three should be used to retrieve the interrupt vector. Writes to this
register are ignored.
