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.

time
OC_SD
1) Not subject to production test, specified by design.
2) Ceramic capacitor.
3) This filter time and its variation is derived from the time base tLP_CLK = 1 / fLP_CLK
4) The absolute voltage value is the sum of parameters VDDC + VDDCSTB
5) The absolute voltage value is the sum of parameters VDDC + VDDCOK
6) After tFILT_VDDCOC_SD is passed and the overcurrent condition is still present the device will enter sleep mode.
