Chapter 6 Applied Instructions API 1204 Symbol: S ： Source device Word D ： Device in which the seven-segment data is stored Word Explanation: The values of the lower 4 bits (b0~b3) in the source device specified by S are decoded as the seven-segment data stored in D . Example: When X0.0 is ON, the values of b0~b3 in D0 are decoded as the seven-segment data stored in Y0.0~Y0.15. If the data in the source device exceeds four bits, the values of the lower 4 bits are decoded. The relation between the seven-segment data and the bit pattern of source data is presented in the following table.
