About this document
Priority Interrupt Structures in 8085A by Alan Dinkley is a document available to read on EtoBox.
The document discusses priority interrupt structures used in microprocessors. It focuses on the 8085A microprocessor, which has 5 interrupt inputs with a fixed priority level from highest to lowest of TRAP, RST7.5, RST6.5, RST5.5, and INTR. When multiple interrupts occur simultaneously, the highest priority interrupt will be serviced first using a priority encoder. The priority encoder identifies the highest priority interrupt and generates a restart instruction to transfer control to the corresponding inte
