Description
When IC is powered up, these all data are set to “0”
0 = output OFF (default)
1 = output ON
8.5.1.3 Control Data Latch
The control data latch is 16-bit in length and contains the Global Brightness Control (BC) Function data, Status
Information Data (SID) load select data, Blank Mode Selection (BLKMS) data, the current value for Invisible
Detection Mode (IDM), IDM working time, and Power-Save Mode enable control data.
When the device is powered up, the data in this data latch are set to the default values shown in Table 8.
The function control data latch configuration is shown in Figure 34.
