This instruction performs a right shift from source device of n 2 registers starting from S todestination device of n 1 registers starting from D.2. This instruction is generally used in pulse execution mode (WSFRP).3. The type of devices designated by S and D has to be the same, e.g. KnX, KnY, KnM, and KnSas a category and T, C, and D as another category4. Provided the devices designated by S and D belong to Kn type, the number of digits of Kn in Sand D has to be the same.5. Valid range of operand n1, n2 : 1≤ n2 ≤ n1 ≤512Program Example 1:1. When X0 is triggered, WSFRP instruction shifts D10~D13 into data stack D20~D35 andD20~D35 also shift to the right with a group of 4 registers.2. The figure below illustrates the right shift of the registers in one scan.
