The user can activate four Control functions. These include: LED
Brightness Level, Prescaler, IC Power Down, or Display Clear.
OPCODEs and six 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 „Load Character
Address“ (page 9) and „Load Column Data“ (page 9).
The user can select eight specific LED brightness levels, Tables
„Display Brightness“ (page 9). Depending on how D3 is selected
either one (1) for maximum peak current or zero (0) for 12.5% of
maximum peak current in the control word per Tables „Display
Brightness“ (page 9), the user can select 16 specific LED bright-
ness levels. These brightness levels (in percentages of full bright-
ness of the display) include: 100% (E0
