PRODUCTION DATA.
The device latches the 205 LSBs of data in the 288-bit common shift register into the FC-BC-DC registers at the rising edge of the latch signal when the 12 MSBs of the 288-bit data are 0.
When the device is powered on, the FC-BC-DC data latch is reset to all 0s. Therefore, data must be written to the 288-bit common shift register and latched into the FC-BC-DC registers before turning on the constant-current outputs. It is better to keep BLANK low to prevent the outputs from turning on.
