8.3.3 Status Information Data (SID)

The status information data (SID) contains the status of the LED open detection (LOD), LED short detection (LSD) and thermal shutdown faults(TSD). When the MSB of the common shift register is set to 0 and the RFRESH bit in the control data latch is 0, the SID are loaded to the common shift register at the LAT falling edge after the data in the common shift register are loaded to the grayscale data latch. If the common shift register MSB is 1, the SID are not loaded to the common shift register.

When the MSB of the common shift register is set to 0 and the RFRESH bit in the control data latch is 1, the SID are loaded to the common shift register at the GS counter 0000h just after LAT when the GS data are input. If the common shift register MSB is 1, the SID are not loaded to the common shift register. When the RFRESH bit is 1, the SCLK rising edge must be input with a low-level LAT signal after 65,538 GSCLKs (or more) are input from the LAT rising signal input.

After being loaded into the common shift register, new SID data cannot be loaded until at least one new bit of data is written into the common shift register. To recheck SID without changing the GS data, reprogram the common shift register with the same data currently programmed into the GS latch. When LAT goes high, the GS data do not change, but new SID data are loaded into the common shift register. LOD and LSD are shifted out of SOUT with each SCLK rising edge. The SID load configuration is shown in Figure 8-4 and Table 8-6.
