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.
