I'm working with the MAx20356EVKIT and There is one functionality that I can't make it work. It is the reporting of the event "UsbOkInt" (generated when a valid voltage is present in CHGIN) via one MPC pin.
I'm setting the MPC pin 6 as an output and in register USBOkItrCfg (0x7E) I'm assigning that event to MPC6.
I generate the interrupt connecting/disconnecting a power supply to CHGIN port. I also have a constant valid voltage in CSN/RSN pin (a battery), so the PMIC is always powered.
And.... nothing is happening. MPC6 pin is not moving.
I tested to report BuckEn (Buck1 to MPC6 pin for instance) and it works perfectly:
MPC6Cfg (0x78) -> 00000100 (Direction set to 1)
Bk1ltrCfg (0x7B) -> 11000000 (Buck 1 PGOOD connected to MPC6)
Buck1Cfg0 (0x31) -> 01010000 (PGOOD comparator enabled)
