= Using Bit-Fields in a MicroBlaze C Project =

We use a very useful C programming tool in the [wiki:802.11 802.11 Reference Design] known as [http://en.wikipedia.org/wiki/Bit_field a Bit-Field]. Bits are not individually addressable in C -- when unaligned access is enabled in a processor, the minimum addressable unit of data is a byte. Bit-fields provide a useful way of interpreting the bits that make up large type definitions. This document is a tutorial on how to use bit-fields in MicroBlaze C projects.
