3.14 Compiler and processor support for bit-banding
The compiler supports bit-banding for processors that provide the feature.
The compiler supports bit-banding in the following ways:
__attribute((bitband))language extension.--bitbandcommand-line option.
Bit-banding is a feature of the Cortex-M3 and Cortex-M4 processors
(
--cpu=Cortex-M3 and --cpu=Cortex-M4)
and some derivatives (for example, --cpu=Cortex-M3-rev0).
This functionality is not available on other ARM processors.Related concepts
