Segment Data Input [Function Mode: 0 to 3]
• MSM9223 receives the segment data when function mode 0 to 3 are selected.
• The same segment data is transferred to the 3 segment data latch correspond to GRID 1 to 3 at
• The segment data is transferred to only one segment data latch that is selected by mode data,
• Segment output (SEG1 to 27) becomes High level when the segment data (S1 to 27) is High level.
[Data Format]
[Bit correspondence between segment output and segment data]
the same time when the function mode 0 is selected.
when the function mode is 1, 2 or 3 is selected.
