Figure 8. LED Diagnostics Configuration
NOTE:
When a channel is configured for LED diagnostics, make sure that the jumpers on the
TLC6C5816EVM are configured properly for the LED diagnostics circuit. Remove the Dx-
OPEN shunt and put on the Dx-DIAG shunt.
There is a CONFIG option in the GUI for the TLC6C5816-Q1 even channels. Selecting NORM means the
channel is in normal ON/OFF operation mode. Selecting DIAG enables the diagnostics function.

Status Read-Back
When the LED diagnostics function is used, the TLC6C5816EVM GUI provides a status check function.
Pressing READ reads back the TLC6C5816-Q1 status register, including LED open or short status,
command error, overtemperature status, and CRC check status. A green indicator means everything is in
the normal state. A red indicator means there is a fault.
