ABSTRACT:
A peripheral device containing a control circuit with internal timing which enables it to independently adjust the timing of an interrupt acknowledge cycle. The circuit senses a timing signal from the CPU and asserts a control signal to suspend the operation of the CPU for a predetermined period of time. The predetermined period of time is customized to the peripheral so that when the CPU is re-activated and reads from the bus, a valid interrupt vector will have been put out by the peripheral.
