WebIt is tristated during local bus “hold acknowledge “. INTA Interrupt Acknowledge: This signal is used as a read strobe for interrupt acknowledge cycles. i.e. when it goes low, the processor has accepted the interrupt. In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without interference from the tri-state buffer. This can be useful in situations w…

WebAn "inout" port of an internal module is just an abstraction, and doesn't actually map to anything, so it is syntactically legal to have a tristate buffer down many levels of logic, and then port the resulting tristated signal up to the top level of your hierarchy (using inout ports), and out of the chip. WebThe meaning of MICROPROCESSOR is a computer processor contained on an integrated-circuit chip; also : such a processor with memory and associated circuits. a computer processor contained on an integrated-circuit chip; also : such a processor with memory and associated circuits… See the full definition WebIn a minimum mode 8086 system, the microprocessor 8086 is operated in minimum mode by strapping its MN/MX* pin to logic1. In this mode, all the control signals are given out by the microprocessor chip itself. There is a single microprocessor in the minimum mode system.
