WebFeb 8, 2013 · Bit-banding is a term that ARM uses to describe a feature that is available on the Cortex M3 and M4 CPU cores. Basically, the device takes a region of memory (the Bit-band region) and maps each bit in that region to an entire word in a second memory region (the Bit-band Alias Region). The benefit of Bit-banding is that a write to a word in the ...

WebFor example, writing to one of the alias words will set or clear the corresponding bit in the bitband region. It appears to be a way to get single bit atomic operation. When writing to the alias regions bit 0 of the 32 bit word is used to set the value at the bit-banding region. Reading from the alias address will return the value from the bit ...
