Correspondence between Display Data (SD1 to SD106) and Segment Output Pins
For example, the table below lists the segment output states for the S11 segment output pin.
BLK and the Display Control
Since the LSI internal data (SD1 to SD106 and DM0 to DM9) is undefined when power is first applied, the display is off
(S1 to S53, G1 and G2 = low) by setting the BLK pin low at the same time as power is applied. Then, meaningless
display at power-on can be prevented by transferring all 144 bits of serial data from the controller while the display is off
and setting BLK pin high after the transfer completes. (See Figure 3.)
Power Supply Sequence
Observe the following sequences when turning the power on and off. (See Figure 3.)
Power on: Logic block power supply (V
DD
) on
→
Driver block power supply (V
FL
) on
Power off: Driver block power supply (V
FL
) off
→
Logic block power supply (V
DD
) off
