8259 programmable interrupt controller (PIC)

8259 programmable interrupt controller (PIC) The 8259 is defined as a programmable interrupt controller (PIC). In 8085 and 8086 there are 5 hardware interrupts and 2 hardware interrupts. By connecting to 8259 in a processor, you can increase the interruptions in processing capacity. 8259 combines multiple input inputs with a single output disruption. The interface […]

Intel 8253 – Programmable Interval Timer

Intel 8253 – Programmable Interval Timer The Intel 8253 and 8254 processors are programmable interval programmers (PTIs) designed for microprocessors to perform timing and counting functions using three 16-bit registers. Each meter has 2 input pins, z. For example, clock and door and 1 pin for the output “OUT”. To operate a counter, a 16-bit […]

Interrupts in 8085

An interrupt is a signal generated by an external device that prompts a microprocessor to perform a task. There are 5 interrupt signals, TRAP, RST 7.5, RST 6.5, RST 5.5 and INTR. Interrupts are subdivided according to their parameters into the following groups: Vector Interrupt – In this type of interrupt, the processor knows the […]
