32.10.2.1 Calculating the Number of Steps When Setting Operands
- SUB/SUBP
The following describes the specifiable content of the (S1, S2,
and D1) operands for the SUB and SUBP instructions.
The actual number of steps in the SUB and SUBP instructions
depends on the specified operand. The following describes how to
calculate the number of steps.
Number of steps in operand S1 + Number of steps in operand S2 +
Number of steps in operand D1 + 1 = Total number of steps in one
instruction
For example, calculating the number of steps
in SUB and SUBP instructions
(For the number of steps in an operand, refer to the operand
settings as follows.)
{Data_1 = 1 step} + {Data_2 [0] = 2 steps} + {Result [Specify
indirectly]= 3 steps} + {1 step} = 7 steps One last step is
included in the instruction. Be sure to add that one step.
