Understanding Microcontrollers: I/O

This lecture delves into the concept of input and output in microcontrollers, focusing on the internal structure of ports and registers. It explains how to manipulate ports using specialized registers, the significance of tristate drivers for input, and the role of registers in storing output values. The lecture also covers the software representation of I/O operations, including writing and reading data from ports. By the end, students will have a clear understanding of how microcontrollers manage input and output signals.
