Contrast (A9)
SMBus Protocol: Read or Write Byte
Input/Output: Byte -- bit flags mapped as follows:
Bit #
7:0
Name
D7-D0
R/W
Default
Description
r/w
0000 Bits D7-D0 contain the contrast level setting. When D7-D0
0000 = FF, the CNT pin of the OZ968 outputs 2.8V. When D7-
D0 = 00, the CNT pin outputs 0.8V.
Brightness (AA)
SMBus Protocol: Read or Write Byte
Input/Output: Byte -- bit flags mapped as follows:
Bit #
7:0
Name
D7-D0
R/W
Default
Description
r/w
0000 Bits D7-D0 contain the brightness level setting. When D7-
0000 D0 = FF, the OZ968 inverter outputs miniimum brightness.
When D7-D0 = 00, the OZ968 inverter outputs maximum
brightness.
