General Device Information
2) Pin TRef was used to control the core voltage generation in step AA. For that step, pin TRef must be connected
to V_DDPB.
This connection is no more required from step AB on. For the current step, pin TRef is logically not connected.
Future derivatives will feature an additional general purpose IO pin at this position.
