8.4.2.1 Output On-Off Data Latch

The output on-off data latch is 24 bits long. This latch is used to turn each output current sink (OUTRn, -Gn, -Bn) on or off. When the MSB of the common shift register is set to 0, the lower 24 bits are written to the output on-off data latch on the rising edge of LAT. If the output on-off data latch bit corresponding to an output is 0, the output is turned off; if the bit is a 1, the output is turned on.

When the device is powered on, the data in the output on-off data latch are not set to any default value. Therefore, the on-off control data should be written to the data latch before the constant-current outputs are turned on.
