7 Application Instructions API 50-99 Operands: S : Source device to be decoded D : Output device after the decoding Explanations: See the specifications of each model for their range of use. Program Example: When X10 = On, the contents (0 ~ F in hex) of the lower 4 bits (b0 ~ b3) of D10 will be decoded into a 7-segment display for output. The decoded results will be stored in Y10 ~ Y17. If the content exceeds 4 bits, the lower 4 bits are still used for the decoding. X10 Decoding table of the 7-segment display:
