C: Control Data
The value of C (0000 to 0007 hex) indicates the number of digits of source data and the logic for the
Input and Output Units, as shown in the following table. (The logic refers to the transistor output's NPN
or PNP logic.)
D: System Word
Specifies a work word used by the instruction. This word cannot be used in any other application.

Function
7SEG(214) reads the source data, converts it to 7-segment display data, and outputs that data (as
leftmost 4 digits D0 to D3, rightmost 4 digits D0 to D3, latch output signals LE0 to LE3) to the 7-
segment display connected to the output indicated by O. The value of C indicates the number of digits
of source data (either 4-digit or 8-digit) and the logic for the Input and Output Units.
7SEG(214) displays the 4-digit or 8-digit data in 12 cycles, and then starts over and continues
displaying the data.
