Electrical Characteristics
29.2
Power Management Unit (PMU)
This chapter includes all electrical characteristics of the Power Management Unit
29.2.1
PMU I/O Supply (VDDP) Parameters
This chapter describes all electrical parameters which are observable on SoC level. For this purpose only the pad-
supply VDDP and the transition times between the system modes are specified here.
