AVR I/O Manipulation in Assembler: Whole Register Operations
General Purpose Input Output (GPIO) are a hallmark of microcontrollers. Here, we talk about assembler operations that affect the entire register, whether it's the PINx, PORTx or DDRx.
These particular slides correspond to Chapter 4 of the textbook, "The AVR Microcontroller and Embedded Systems Using Assembly and C: Using Arduino Uno and Atmel Studio."
The original slides and the main reference book can be found by the original author, Sepehr Naimi. See his website, https://nicerland.com, as well as co-author's website: http://www.microdigitaled.com
