Let%27s dive into the fascinating world of bit manipulation instructions in microcontrollers (MCUs).
1. What are Bit Manipulation Instructions?
- Bit manipulation refers to the process of directly manipulating individual bits within a data word (usually an integer or a register).
- MCUs provide specialized instructions to perform bitwise operations efficiently.
- These instructions allow you to set, clear, toggle, or check specific bits within a register or memory location.
2. Common Bit Manipulation Operations:
- Setting a Bit (Bitwise OR):
- To turn on a specific bit, use the bitwise OR operation (`|`).
- Example: If you want to set the 3rd bit of a register `R`, you can do `R |= (1
