Hi team,
I connect the enable pin to refB directly. The datasheet requires the EN pin input voltage should not higher than refA. However, as I check, the function works good. Can you tell me what will happen?
For more information, the SDA_BT and SCL_BT have pull-up resistor on other board. For the IRQ pin, the signal only comes from 3V3 part to 1V8 part.
