Chapter 6 Applied Instructions Symbol S ： Source device D ： Device where the seven-segment data is stored Explanation The instruction decodes the values of the lower four bits (b0–b3) in the source device specified by S as the seven-segment data stored in D . 6_ Example When X0.0 is ON, the instruction decodes the values of b0–b3 in D0 as the seven-segment data stored in Y0.0–Y0.15. If the data in the source device exceeds four bits, the instruction decodes the values of the lower four bits.
