This chip is like this: we set the interrupt output angle of 4310 to high by default. But when we tested, it was always low frequency, and it is estimated that it was pulled down by 4310. Then, we welded two boards, and the two boards were in the same state. One has always been high and the other is low, now equivalent to two boards, but the state of 4310 is different.
And then the 4310 we tested earlier seemed to be high-frequency, all high-frequency. I remember it used to be high frequency, and then we kept running the data, and 4310 became low frequency, even interruptions became low frequency.
What is the reason for this?
