Selected target does not support bit-banding
WebA mapping formula shows how to reference each word in the alias region to a corresponding bit, or target bit, in the bit-band region. The mapping formula is: bit_word_offset = … WebNov 12, 2024 · 4. The bit specific address is an alias for an operation conducted on a specific bit of an address in the bit band target region. If you wish to make a simultaneous change to multiple bits, you should not use the bit-band alias, but some other mechanism. This might be a traditional read-modify-write operation.
