Bits 00 to 06 specify the Unit to which the characters will be output (specifics are
shown in the following diagram). Bit 07 determines whether the source data is
hexadecimal (OFF) or 7-segment display code (ON). Bit 08 determines whether
the characters will flash (ON) or not (OFF).
If bit 09 of C is set for automatic display (ON), the characters will be displayed
regardless of the Unit’s display mode, but if bit 09 of C is OFF, the characters will
be displayed only when the Unit is set to display mode 3.

If bit 07 is set for hexadecimal data, the characters are output as they are in the
source word. The rightmost digit will be the rightmost on the display.
If bit 07 is set for 7-segment display code, segments a to f of the leftmost digit are
contained in S bits 00 to 06, segments a to f of the second digit are contained in S
bits 08 to 14. Set bits 07 and 15 to zero. The segments for the third and fourth
digits follow the same pattern in word S+1, as shown in the following diagram.
The table shows the number of the bit that must be turned ON in S or S+1 to turn
ON each segment of each digit in the display.
Segment g f e d c b a
S Digit 1 06 05 04 03 02 01 00
Digit 2 14 13 12 11 10 09 08
S+1 Digit 3 06 05 04 03 02 01 00
Digit 4 14 13 12 11 10 09 08
S cannot be the last word in a data area when S and S+1 contain 7-segment
display code.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
Control word data is incorrect.
The following example show how to produce the display “a051” from both a
7-segment display code.
When CIO 000000 is ON, the content of CIO 0200 and CIO 0201 is displayed
according to the specifications in D15000.
