Status Information Data (SID)
The AS1121 contains an integrated status information register, which can be accessed in greyscale mode (MODE = GND). Once the LD signal
latches the data into the greyscale register, the input shift register data is replaced with status information data
The Open LED information as well as the dot-correction registers can be read out at pin SDO. The status information data packet is 192 bits
wide. Bits 31:16 contain the open LED detection status of each channel. Bits 167:72 contain the data of the dot-correction register. The remain-
ing bits are reserved. The complete status information data packet is shown in
