PRODUCTION DATA.
The TLC6C5816-Q1 device has a 24-bit configuration register. Data transfers through the shift registers on the rising edge of SRCK and latches into the storage registers on the rising edge of RCK. The first 8 data bits control the diagnostics channel configuration, and the following 16 data bits control 16 open-drain outputs independently.
The DRAINn+1-DIAGn channel configuration is controlled by the DIAGn registers. These channels can be set to either open-drain output or diagnostics input mode. The TLC6C5816-Q1 device does not allow the user to set DRAINn+1 and DIAGn high at the same time, because the divider resistor for LED diagnostics can result in leakage current on the LED, which lights up the LED. If the DIAGn and DRAINn registers are set to high at the same time, the channel operates as an open-drain output instead of LED diagnostics, and a command error latches in the fault registers, which can be read back by the register readback function as explained in Register Read.
