    tanaka.noriyoshi001_1698376

      Situation

         Using device MB9BF368N

         I tried to set of P46/P47/P48/P49 (VBAT Domain)  as GPIO(Input) with pull-up.

       

      Problem

         P46/P47 pull-up setting is OK,   P48/P49 pull-up setting is FAIL

       

       *Register Setting is as follows

             VBPFR = 0x00,  VBDDR = 0x00,  VBPCR = 0x0F

       

      Is this device's problem ? (or sillicon errata?)

       

      thank you,
