So today we will see that what is interrupts in microprocessor 8085 in my early post we had discussed on the topics like what is a microprocessor. There is eight software interrupts in 8085 microprocessor starting from rst 0 to rst 7 they allow the microprocessor to transfer program control from the main program to the subroutine.

Interrupts of 8085

Interrupt is the mechanism by which the processor is made to transfer control from its current program execution to another program having higher prio. The trap instruction is a non-maskable interrupt provision for the 8085 there is no mask bit related to it, and no control bits of any kind it is used for interrupts of a catastrophic.

An interrupt in the 8085, like in most computers, is a request to execute code out of sequence, usually by an external event, such as a signal from an io device. Answer: the 8085 microprocessor has five interrupt inputs they are trap, rst 75, rst 65, rst 55, and intr t. Interruptsthe interrupt i/o is a process of data transfer whereby an external device or a peripheral can inform a proccessor that it is ready for communication and it request attentionthe. Interrupts in a typical computer system, the software can be divided into 3 possible groups one is the operating loop, another is the interrupt service routines, and the last is the bios/os.
