12.6.3.1 Operands
An instruction operand can be an ARM register, a constant, or another instruction-specific parameter. Instructions
act on the operands and often store the result in a destination register. When there is a destination register in the
instruction, it is usually specified before the operands.
Operands in some instructions are flexible, can either be a register or a constant. See
