Brightness Control
Brightness is controlled by controlling the “on time” duty cycle. The device allows for 16 bright-
ness steps as illustrated in list 3 with 0/16 as the dimmest setting (not illuminated) to 15/16 as
the brightest setting. The duty cycle control register is addressed with a 20 Hex command at
D15~D8 and the appropriate data per list 3 at D3~D0. D7~D4 are not recognized by the duty
cycle register. The initial state, upon power up is 15/16, or full brightness.
“x” indicates that data is required in this field to execute the function. “-” indicates that data in
this field is not required and not recognized.
