3 The Cortex-M3 Instruction Set
3.1 Instruction set summary
The processor implements a version of the Thumb instruction set. Table 3.1 (p. 33) lists the supported
instructions.
Note
angle brackets, <>, enclose alternative forms of the operand
braces, {}, enclose optional operands
the Operands column is not exhaustive
Op2 is a flexible second operand that can be either a register or a constant
most instructions can use an optional condition code suffix.
For more information on the instructions and operands, see the instruction descriptions.
