External signal description
14.5.2 Full performance mode
In the full performance mode (FPM) state, the four regulators of PMC perform full
regulation of the input supply, to produce the internal regulated supplies in the chip.
14.6 External signal description
PMC has one input signal channel. The following table itemizes all the PMC external
pins.

14.6.1 VDD
VDD is the PMC integrated regulator power supply voltage pin. This is the voltage
supply input from which the voltage regulator generates the on-chip voltage supplies. An
external decoupling capacitor is required on this pin.
14.6.2 VDDX
VDDX is the 5 V voltage regulator (VREG
I/O drivers.
14.6.3 VREFH
VREFH is the accurate voltage reference (VREG
from 3.7 V to 4.9 V. An external decoupling capacitor is required on this pin.
