3.3 About the instruction descriptions
This section gives more information about using the instructions.
3.3.1 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 in that they can either be a register or a constant. See
3.3.2 Restrictions when using PC or SP
Many instructions have restrictions on whether you can use the Program Counter (PC) or Stack Pointer
(SP) for the operands or destination register. See instruction descriptions for more information.
Note
Bit[0] of any address you write to the PC with a BX, BLX, LDM, LDR, or POP instruction must
be 1 for correct execution, because this bit indicates the required instruction set, and the
Cortex-M3 processor only supports Thumb instructions.
3.3.3 Flexible second operand
Many general data processing instructions have a flexible second operand. This is shown as Operand2
in the descriptions of the syntax of each instruction.
Operand2
can be a:
3.3.3.1 Constant
You specify an Operand2 constant in the form:
