Dear Expert
The problem is that we added a large current to the infrared LED, and then AFE4400 detected the fault. Then we removed the large current, and pulled the AFE chip to reset the AFE chip to reconfigure the register, but the fault of the AFE chip was still detected .
However, we short-circuited two pins, reported the fault, and then pulled the AFE chip to reconfigure the register, which could not be restored to normal. But the power to restart the whole machine can be restored to normal
