Hello all!

Have strange behavior of PMIC MMPF0100F0AEP:

For the first time I've connected to my board with PF Series Programmer, KITPFGUI (rev4.1) read PMIC config, showed all states and voltages but all output voltages except 5V from SWBST are resetting every 30ms. And even when I changed some voltage levels in KITPFGUI they weren't changed on outputs.

Then I disconnected PMIC from load so it should be no voltage LDO power inputs but there was about 4V on VIN1.

The same problem on the second board.
