Bit band alias calculator
WebBit-band operations are only possible in the bit-band regions where the LSB of each word represents a single bit in a bit-band alias region. The term "bit-band alias" describes the registers or memory locations to which the bus performs the actual read-modify-write operation. In other words, if a programmer wants to perform a bit operation on a ... WebNov 12, 2024 · 4. The bit specific address is an alias for an operation conducted on a specific bit of an address in the bit band target region. If you wish to make a simultaneous change to multiple bits, you should not use the bit-band alias, but some other mechanism. This might be a traditional read-modify-write operation.
