About this document
Understanding ARM Bit-Banding Features by rumralkar is a document available to read on EtoBox.
This document discusses bit-banding, a feature of ARM Cortex-M3/M4 microcontrollers that allows direct, atomic access to individual bits in memory. Bit-banding maps each bit in a 1MB region of memory to a separate word in an alias region, allowing hardware-assisted read-modify-write operations. This improves on the inefficiency of bitfields and enables easier access to peripheral registers at the bit level. Examples show how to calculate bit-band addresses and use it to set pin values based on a button pres
