WebIt remaps bit-band alias addresses to the bit-band region. For reads, it extracts the requested bit from the read byte, and returns this in the Least Significant Bit (LSB) of the read data returned to the core.. For writes, it converts the write to an atomic read-modify-write operation. WebAlso, reading a word in the alias region will return the value of the corresponding bit in the Bit-band region. These operations take a single machine instruction thus eliminate race …

Bit Band operations with ARM Cortex microcontrollers; Bit-banding Explained: A Key Feature of ARM Cortex-M3/M4; WebThis is called 'mapping' and the bit-band address region is called an 'alias'. Seems strange, doesn't it. If the HSION bit is set, then its address in the bit-band region contains the value 0x00000001 (a 4-byte location for every aliased bit); if it is reset, then the corresponding value in the bit-band region is 0x00000000.
