Abstract
A circuit for preventing a non-conforming PCI bus master from performing cycles where the address driven is not provided soon enough for receiving circuitry to latch the address. The circuit modifies the bus grant signal to force the non-conforming PCI bus master to temporarily release the bus instead of performing a second data transfer cycle within the same bus access so that a conforming cycle is subsequently performed when the bus is reacquired by the non-conforming PCI bus master. The circuit forces the non-conforming PCI bus master off the bus even though the non-conforming PCI bus requests the bus and an arbiter has granted the bus to the non-conforming PCI bus master.
