Program Plan Intro
Bit Shift Register:
- Bit shift register refers to a register that is used to shift the bits through a single or group of registers serially.
- There are two different bit-shift instructions, namely,
- Bit Shift Left (BSL)
- Bit Shift Right (BSR)
- Shift registers are capable of storing the status of an event or values through data files.
