标题: [M480] M4 Bit-Banding
[size=1.1em]Bit-banding is a feature of the Cortex-M4 processor that maps each word in an alias region of memory to a bit in a bit-band region of memory. This allows an individual bit in SRAM or peripheral register to be set/cleared by a single instruction that increases the operation speed.

This sample demonstrates how to use Bit-banding operation in C with a simple pre-processor macro to perform the accesses.
