3.8 Counting Step Number
*1: If the same device is used for and , the number of basic steps increases by one.
*2: The number of steps decreases with a standard device register.
When multiple standard device registers are used in an instruction applicable
to subset processing, the number of steps decreases. The following table
shows the number of steps for each instruction.
*1: If the same device is used for and , the number of basic steps increases by one.
