5.8.4 SEGD (FNC 73)
Operation:
A single hexadecimal digit (0 to 9, A to F)
occupying the lower 4 bits of source device S is
decoded into a data format used to drive a seven
segment display. A representation of the hex digit
is then displayed. The decoded data is stored in
the lower 8 bits of destination device D. The upper
8 bits of the same device are not written to. The
diagram opposite shows the bit control of the
seven segment display. The active bits correspond
to those set to 1 in the lower 8 bits of the
destination device D.
