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 Charac-
ter Address and Loading Column Data are shown in Tables 2
and 3.

Previously “on” LED
The user can select seven specic LED brightness levels,
Table 4. These brightness levels (in percentages of full bright-
ness 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 chang-
ing the duty factor of the row strobe pulse.
Table 4. Display brightness
The SCD558X offers a unique Display Power Down feature
which reduces ICC to less than 50 A. When FFHEX is loaded,
as shown in 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 dis-
play is reactivated by loading a new Brightness 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.
