The user can activate four Control functions. These include:
LED Brightness Level, Lamp Test, IC Power Down, or Display
Clear. OPCODEs and five 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 specific LED brightness levels,
Table 4. These brightness levels (in percentages of full bright-
ness of the display) include: 100% (F0
HEX
), 53% (F1
HEX
),
40% (F2
HEX
), 27% (F3
HEX
), 20% (F4
HEX
), 13% (F5
HEX
), and
6.6% (F6
HEX
). 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 I
CC
to less than 50
μ
A. When FF
HEX
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 F8
HEX
, 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.
