Bit banging is a technique to interface with external devices using standard input/output operations. It involves manually manipulating I/O pins to generate signals, such as for SPI communication when hardware modules are not available. This software-based approach provides direct control over the interface, avoiding the need for specialized hardware. [Original content shortened for length]

Bit-banding in ARM Cortex-M architectures simplifies the manipulation of individual bits within memory or peripheral registers, addressing complexities and inefficiencies. By providing direct access to specific bits through the alias region, it ensures atomicity and efficiency, avoiding the risk of data corruption. This feature significantly streamlines embedded systems development and enhances reliability.
