Ok there is a PDR_ON pin which i can see is the Power Down Reset pin.... but how does one connect to it?
I tried following the schematic on the STM32F4-Discovery board but it tells me R27 isnt fitted.. i assume that means its not populated and it says nothing on R28. Both resistors touch the PDR_ON pin. So im not sure what to follow?
Should i do whats on the board and FIT a 0 ohm or straight connect VDD.... ? or listen to schematic and tie to GND?
Im kind of lost... Attached are pictures of the schematic portion from the Discovery Datasheet and the actual board image where R27 is in place but not R28...
Perhaps its a silk screen error?
