摘要：A data processing device is used with peripheral devices having addresses anddiffering communication response periods. The data processing device includes a digitalprocessor adapted for selecting different ones of the peripheral devices by assertingaddresses of each selected peripheral device. Addressable programmable registers holdwait state values representative of distinct numbers of wait states corresponding todifferent address ranges. Circuitry responsive to an asserted address to the peripheraldevices asserted by the digital processor generates the number of wait statesrepresented by the value held in one of the addressable programmable registerscorresponding to the one of the address ranges in which the asserted address occurs,thereby accommodating the differing communication response periods of the peripheraldevices.
