The following describes the specifiable content of Operands (D1 and D2) in the XCH and XCHP instructions
The actual number of steps in the XCH and XCHP instructions depends on the specification method of the operand. The following describes how to calculate the number of steps.
Number of steps in operand D1 + Number of steps in operand D2 + 1 = Total number of steps in one instruction
For example, calculating the number of steps in XCH and XCHP instructions.
(For the number of steps in an operand, refer to the operand settings as follows.)
{Data_1 = 1 step} + {Data_2 = 1 step} + {1 step} = 3 steps One last step is included in the instruction. Be sure to add that one step.
