13: SHIFT / ROTATE INSTRUCTIONS« FC4A MICRO SMART USER ’S MANUAL » 13-5WSFT (Word Shift)Applicable CPU ModulesValid OperandsFor the valid operand number range, see pages 6-1 and 6-2.When T (timer) or C (counter) is used as S1 or S2, the timer/counter current value is read out.Valid Data TypesSpecial Internal Relay M8024: BMOV/WSFT Executing FlagWhile the BMOV or WSFT is executed, M8024 turns on. When completed, M8024 turns off. If the CPU is powered downwhile executing BMOV or WSFT, M8024 remains on when the CPU is powered up again.Example: WSFTFC4A-C10R2/C FC4A-C16R2/C FC4A-C24R2/C FC4A-D20K3/S3 FC4A-D20RK1/RS1 & FC4A-D40K3/S3— — — — XOperand Function I Q M R T C D Constant RepeatS1 (Source 1) Source data for word shift X X X X X X X X —S2 (Source 2) Quantity of blocks to shift X X X X X X X X —D1 (Destination 1) First operand number to shift — — — — — — X — —W (word) I (integer)X —When input is on, N blocks of 16-bit word data starting with operanddesignated by D1 are shifted up to the next 16-bit positions.
