In this tutorial, we dive deep into the BLX (Branch with Link and Exchange) instruction using the NXP LPC2919 microcontroller and the Keil uVision IDE.
What you will learn in this video:
The Theory: What the BLX instruction does and how it affects the CPSR (Current Program Status Register).
Step-by-Step Coding: Writing assembly code to demonstrate a branch from ARM to a Thumb subroutine.
Debugging: Using the Keil Simulator to watch the "T" bit in the register window change during execution.
