The value of C indicates the number of digits of source data and the logic for
the Input and Output Units, as shown in the following table.
If there are 8 digits of source data, they are placed in S and S+1, with the
most significant digits placed in S+1. If there are 4 digits of source data, they
are placed in S.
7SEG(88) displays the 4 or 8-digit data in 12 cycles, and then starts over and
continues displaying the data.
Refer to page 424 for more information on 7SEG(88) and its applications.
Flags ER: S and S+1 are not in the same data area. (When set to display 8-digit
data.)
Indirectly addressed EM/DM word is non-existent.

There is an error in operand settings.
SR 25409: ON while 7SEG(88) is being executed.
Hardware The 7-segment display is connected to an Output Unit as shown in the dia-
gram below. For 4-digit display, the data outputs (D0 to D3) are connected to
output points 0 through 3, and latch outputs (CS0 to CS3) are connected to
output points 4 through 7. Output point 12 (for 8-digit display) or output point 8
(for 4-digit display) will be turned ON when one round of data is displayed, but
there is no need to connect them unless required by the application.
