Hi,

Manual describes reset cause in RSTSTAT register, but description is not complete. What means PV reset? I am unable find this reset cause.

If I trigger software reset I get RSTSTAT=8 this is OK. If I power on board I get 7, bits PORST, SWD,PV set, why not only PORST? Sometimes I get 9, PORST and CPU system reset set?

Can someone explain 7 and 9?

it seems that there are internal documents, which are not disclosed to the customers.
