PL see the picture below:

what's the state of FCCU0 and FCCU1  ("0" or "1"),  when an error occurs ?

I want to add leds to indicate the state of FCCU0 and FCCU1, where can I add them?

if FCCU0 and FCCU1 have the ability to drive the LED(about 2mA) ?

Thank you for your answer !

Hi, if you use bi-stable protocol, then you could possibly use these signal for driving LEDs.

I would recommend to drive base of the transistor and put LED to the collector of the transistor. Of course, some resistors will be needed to use to set right working point.

Here I have found some article for inspiration:

Driving an LED using a Transistor 

Hope it helps
