SBFX extracts a bitfield from one register, sign extends it to 32 bits, and writes the result to the
destination register.
UBFX extracts a bitfield from one register, zero extends it to 32 bits, and writes the result to the
destination register.
Do not use SP and do not use PC
These instructions do not affect the flags.
