IO and Interrupts: Connecting Peripherals and Handling Interrupts

This lecture covers the connection of input and output peripherals to a processor, including reading button states and displaying characters on a seven-segment display. It also explains how interrupts are used to handle external events, with a focus on interrupt priority levels and interrupt acknowledgment. The instructor demonstrates how to modify the button interface to generate interrupts and provides a detailed explanation of the interrupt handling process, including the main exception handler and the Interrupt45 routine.
