Table 4. Display brightness
The SCDV554X offers a unique Display Power Down feature
which reduces ICC to less than 50
A. When FF
HEX is loaded
(Table 5) the display is set to 0% brightness and the internal
multiplex clock is stopped. When in the Power Down mode data
may still be written into the RAM. The display is reactivated by
loading a new rightness Level Control Word into the display.
Table 5. Power down
The Lamp Test is enabled by loading F8HEX, Table 6, into the
serial shift register. This Control Word sets all of the LEDs to a
53% brightness level. Operation of the Lamp Test has no affect
on the RAM and is cleared by loading a Brightness Control Word.
Table 6. Lamp test
The Software Clear (C0HEX), given in Table 7, clears the
Address Register and the RAM. The display is blanked and the
Character Address Register will be set to Character 0. The
internal counter and the Control Word Register are unaffected.
The Software Clear will remain active until the next data input
cycle is initiated.

Table 2. Load character address
Table 3. Load column data
The user can activate four Control functions. These include:
LED Brightness Level, Lamp Test, IC Power Down, or Display
Clear. OPCODEs and ve bit words are used to initiate these
functions. The OPCODEs and Control Words for the Character
Address and Loading Column Data are shown in Tables 2 and 3.
The user can select seven specic LED brightness levels, Table
4. These brightness levels (in percentages of full brightness of
the display) include: 100% (F0HEX), 53% (F1HEX), 40% (F2HEX),
27% (F3HEX), 20% (F4HEX), 13% (F5HEX), and 6.6% (F6HEX).
The brightness levels are controlled by changing the duty factor
of the row strobe pulse.
