Bit band operation
WebJul 9, 2024 · Of course, as we've seen, bit-banding can be used on any register bit in the peripheral address space, so dedicated macros can be used to not only clear an … WebThe bit band mechanism works by using a separate memory region called the bit-band alias. Alias regions are located far from available RAM or actual peripherals. As you can …

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.
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..
