The processor implements a version of the thumb instruction set. Table 20 lists Table 20. Cortex-M3 instructions. Mnemonic. Operands. Brief description. Flags.
The opcode is the instruction. The number of operands in an instruction depends on the type of instruction. Normally, the first operand is the destination of theCortex-M3 instructions The processor implements the ARMv7-M Thumb instruction set. shows the Cortex-M3 instructions and their cycle counts. of cycles required based on the number of leading ones and zeroes in the input operands.
