We are using TPA6404 Class-D Audio Amplifier. During cyclic diagnostics we are performing short to ground(S2G) on Rear Left speaker(RL). When we read the data from the 0x0C register we encountered that along with the short to ground, short to power and sometimes open load is being set. Our expectation is only short to ground bit should be set.
This issue is seen sporadically but it is often. Sometimes issue is seen at first instance of short to ground only and only short to ground is seen.
Thanks & Best Regards,
