3 CONFIGURATION OF INSTRUCTIONS
3.8 Counting Step Number
*1 If the same device is used for (S1) and (S2), the number of basic steps increases by one.
*2 The number of steps decreases with a standard device register.
*3 Not available with LCPU.
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.
*4 If the same device is used for (S1) and (D), the number of basic steps increases by one.
DMOV, DMOVP, EMOV, EMOVP Serial number access format file register, Extended data
register (D), Extended link register (W)
