O is a process of data transfer where-by an external device or a peripheral can inform the microprocessor that it is ready for communication. The interrupt requests are classified in two categories: 1.Maskable interrupt request can be ignored or delayed by the microprocessor and used in telephone. 2 .

I. INTRODUCTION (HEADING 1). A device requiring attention of CPU uses interrupts to denote that it require immediate service of CPU. After saving the flag registers, the instruction pointer and other registers like code segment register onto the stack, CPU reaches a prespecified location where service routine of concerned.
28 May 2010 Interrupt Structure in 8085. Interrupt is signals send by an external device to the processor, to request the processor to perform a particular task or work. Mainly in the microprocessor based system the interrupts are used for data transfer between the peripheral and the microprocessor. The processor will
Unsourced interrupt in 8085 microprocessor pdf may be challenged and removed. 12 V supplies needed by the 8080. 8080-derived CPU introduced the year before. However, an 8085 circuit requires an 8-bit.
