When one hexadecimal digit (4 bits) is shifted to the left,
− The data in hexadecimal digit position 4 (bit positions 12 to 15) of the 16−bit data specified by D is
shifted out and is transferred to the lower digit (bit positions 0 to 3) of special data register DT9014
(with the FP0 T32, FP0R, FPΣ,FP−X, FP2, FP2SH and FP10SH: DT90014).
− The hexadecimal digit position 1 (bit positions 0 to 3) of the 16-bit data specified by D becomes 0.
Flag conditions
・Error flag (R9007): Turns on and stays on when the area specified using the index modifier
exceeds the limit.
・Error flag (R9008): Turns on for an instant when the area specified using the index modifier
exceeds the limit.
