Hi Expert,
I have two question for LM8330. Would you help it?
1. The RESETN pull high 2.2Kohm. My GPIO can't pull down it, even I used 10Kohm, it doesn't work. So, I remove the resistor, use the GPIO control only. Any idea for it?
2. When I initial LM8330 by the below code, I can read "IRQST" changed, but IRQN pin always be high. Andy idea for it? Thanks!
