Note:
*1: Refer to section 5.1 for more information on instructions STL and RET.
*2: The execution speed is obtained by basic test programs, therefore the actual instruction
execution time could be longer due to a more complicated program, e.g. program contains multiple
interruptions or high speed input/output.
