Memory Addressing Modes of 8086: Most of the memory ICs are byte oriented i.e. each memory location can store only one byte of data. The 8086 is a 16-bit microprocessor,…
Maximum Mode Configuration of 8086: A processor is in the Maximum Mode Configuration of 8086 when its MN/MX pin is grounded. The maximum mode defines pins 24 to 31 as…
Minimum Mode Configuration of 8086: Pin definitions from 24 to 31 are different for minimum mode and maximum mode. By using these pins the 8086 itself generates all bus control…
8086 Microprocessor Pin Diagram and 8088 Pin Diagram: In order to implement many situations in the microcomputer system the 8086 Microprocessor Pin Diagram and 8088 Pin Diagram has been designed…
8086 Interrupts Articles: Interrupt Structure of 8086: An Interrupt Structure of 8086 can come from any one the three sources : External signal Special Instruction in the program Condition produced…
Interrupt Priority in 8086: As far as the Interrupt Priority in 8086 are concerned, software interrupts (All interrupts except single step, NMI and INTR interrupts) have the highest priority, followed…
8086 Interrupt Types: The 8086 Interrupt Types are Dedicated Interrupts: Type 0 : Divide by Zero Interrupt When the quotient from either a DIV or IDIV instruction is too large to…
Interrupt Structure of 8086: An Interrupt Structure of 8086 can come from any one the three sources : External signal Special Instruction in the program Condition produced by instruction External…
