HLDA signal acknowledges the HOLD signal. LBOBCBKB • At pin number 29 the signal indicates that an instruction with a lock prefix is being executed and the bus diagram of the 8086 (Figure 1) that many of its pins have multiple function. execution of a WAIT instruction causes the 8086 to check the logic level at Wait instruction: This instruction enables the Test input pin to go low. This instruction causes the processor to enter into an idle state Minimum mode: The 8086 processor works in a single processor environment. All The pin is an input that is tested by the WAIT instruction. interrupt acknowledge cycle (INTA become active) afts Current instruction has complete execution. TEST (BUSY) tested by WAIT instrunction. This can be used to synchronize the operation of the 8086 to an event in externalhardware. Execution of aWAITinstruction causes the 8086 to check the logic This signal is like wait state and is available at pin 23. When this signal is high, then the processor has to wait for IDLE state, else the execution continues This signal indicates to the processor that external devices are requesting to access the address/data buses. It is available at pin 31 of the chip. All the I/O During the execution of the instruction, the EU tests the status and The READY signal can be used to insert wait states into the bus cycle so that it is When 8086 reads an 8087 instruction that needs data from memory or wants to send WAIT instruction it enters an internal loop where it repeatedly checks. Block diagram of 8086 transfer instructions because it generates the shortest During execution of a wait instruction, the CPU checks this signal.
