Setting Greyscale Brightness
The brightness of each channel output can be adjusted using a 12 bits-per-channel PWM control scheme which results in 4096 brightness steps,
from 0% to 100% brightness. The brightness level for each output is calculated as:
%Brightness =
GS n
4095
x 100
(EQ 4)
Where:
GS n is the programmed greyscale value for OUT n (GS n = 0 to 4095);
n = 0 to 15 greyscale data for all outputs.
The device powers up with the following default seetings: GS = 4095 and DC = 63.
The input shift register shifts greyscale data into the greyscale register for all channels simultaneously. The complete greyscale data format con-
Note: The data packet must be clocked in with the MSB first.

When pin MODE is tied to GND, the AS1112 enters greyscale data input mode. The device switches the input shift register to 192-bit width. After
all data is clocked in, the rising edge of the LD signal latches the data into the greyscale register (see Figure 14) .
All greyscale data in the input shift register is replaced with status information data (SID) after latching into the greyscale register.
