Functions

VFQFN56

VDD18_MVR[1,2]

Pwr

Digital supply voltage for main voltage regulator (1.8 V)

31,4

VDD12_MVR[1,2,3]

Pwr

Digital supply voltage for core circuitry (1.2 V). When using the MVR,

this pin shall not be driven by an external voltage supply, but a

capacitance shall be connected between these pins and GND to

guarantee on-chip voltage stability.
