Bit-band objects must not be placed outside bit-band regions.
If you do inadvertently place a bit-band object outside a bit-band
region, either using the at attribute, or using
an integer pointer to a particular address, the compiler responds
as follows:
If the
bitbandattribute is applied to an object type and--bitbandis not specified on the command line, the compiler generates an error.If the
bitbandattribute is applied to an object type and--bitbandis specified on the command line, the compiler generates a warning, and ignores the request to bit-band.If the
bitbandattribute is not applied to an object type and--bitbandis specified on the command line, the compiler ignores the request to bit-band.
