WebJan 7, 2024 · Bit_number is the bit position (0-7) of the targeted bit. Links. 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.
