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.
