Electrical Characteristics
29.2.2 PMU Core Supply (VDDC) Parameters
This chapter describes all electrical parameters which are observable on SoC level. For this purpose only the core-
supply VDDC and the transition times between the system modes are specified here.

2) Ceramic capacitor.
3) This filter time and its variation is derived from the time base t_{LP_CLK} = 1 / f_{LP_CLK}.
4) The absolute voltage value is the sum of parameters V_DDC + V_DDCSTB.
5) The absolute voltage value is the sum of parameters V_DDC + V_DDCOK.
6) After t_{FILT_VDDCOC_SD} is passed and the overcurrent condition is still present the device will enter sleep mode.
