Basic I/O Unit Instructions
Section 3-23
Description
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.
The One Round Flag (bit 08 of O when converting 4 digits, bit 12 of O when
converting 8 digits) is turned ON for one cycle in every 12 cycles after
7SEG(214) has turned ON each of the latch output signals. After the 7-seg-
ment data is output in 12 cycles, 7SEG(214) starts over and converts the
present contents of the source word(s) in the next 12 cycles.
When executed, 7SEG(214) begins on latch output 0 at the beginning of the
round, regardless of the point at which the last instruction was stopped.
Even if the connected 7-segment display has fewer than 4 digits or 8 digits in
its display, 7SEG(214) will still output 4 digits or 8 digits of data.
External Connections
Connect the 7-segment display to the Output Unit as shown in the following
diagram. This example shows an 8-digit display. With a 4-digit display, the
data outputs (D0 to D3) would be connected to outputs 0 to 3 and the latch
outputs (LE0 to LE3) would be connected to outputs 4 to 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 has been output, but it is not necessary to connect
them unless required by the application.
