Interrupt Control Registers
The Z8 allows up to six different interrupts from a variety of sources. These inter-
rupts can be masked and their priorities set by using the Interrupt Mask Register
and Interrupt Priority Register. The Interrupt Request Register stores the interrupt
requests for both vectored and polled interrupts.
