Detailed Open-LED Error Report
The detailed open-LED error report can be read out immediately after global error mode has been run. SDI must be 1 for the first device.

Detailed Open-LED Error Report Example
Consider a case where three AS1110s are cascaded in one chain. A 1 indicates a LED is on, a 0 indicates a LED is off, and an X indicates an
open LED. The open-LED test is only applied to LEDs that are turned on. This test is used with a test pattern where all LEDs are on at test time.
IC1:[1111111111111111] IC2:[111XX11111111X11] IC3:[1111111111111111]
IC2 has three open LEDs switched on due to input. 3*16 clock cycles are needed to write the entire error code out. The detailed error report
would look like this:
Input Data: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
LED Status: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
Failure Code: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

1111111111111111
Comparing this report with the input data indicates that IC2 is the device with two open LEDs at position 4 and 5 and one open LED at position
14. For such a test it is recommended to enter low-current diagnostic mode first (see Low-Current Diagnostic Mode on page 15) to reduce screen
flickering.
This test can be used also on-the-fly without using an all 1s test pattern (see Figure 19 on page 17) .
Note: In an actual report there are no spaces in the output. LEDs turned off during test time cannot be tested and will show a logic 1 in the
detailed error report.
