2.4 Basic instructions
2.4.2 Arithmetic operation instructions
*1: The number of steps may vary depending on the device and type of CPU module being used.
Note 1) When using a High Performance model QCPU, Process CPU or Redundant CPU,
the number of steps increases but the processing speed becomes faster.
Note 2) The number of steps may increase due to the conditions described in Section 3.8.
*2: The number of steps may vary depending on the device and type of CPU module being used.
Note 1) When using a High Performance model QCPU, Process CPU or Redundant CPU,
the number of steps increases but the processing speed becomes faster.
Note 2) The number of steps may increase due to the conditions described in Section 3.8.
*3: The number of steps may vary depending on the device and type of CPU module being used.
Note 1) The number of steps may increase due to the conditions described in Section 3.8.
*4: The number of basic steps is three for the Universal model QCPU only.
