WebDec 1, 2011 · The first bit in the 'bit-band' peripheral memory is mapped to the first word in the alias region, the second bit to the second word etc. Writing a value to the alias region with Least Significant Bit i.e. bit [0] set to 1 will write a value of 1 to the bit-band bit. Conversely writing a value of 0 will clear the bit-band bit. 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 ...

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 ...
