JP8

VDD_LV – power supply for the PLL and cores (VDD_LV_PLL and VDD_LV_CORE)

1-2

The VCORE coming from the motherboard is used directly – if this option is used, the VCORE on

the motherboard must be configured to 1.2 V, otherwise the MCU can be damaged!

2-3

The VDD_LV_xxx will be supplied from VCOREcoming from motherboard using an external ballast

to generate 1.2 V (VCORE is configured on the motherboard to 3.3 V).

JP9

VDD_HV – power supply for the MCU’s IOs (VDD_HV_IO and some other peripherals

– see schematics for details)

1-2

The VCORE is used (is configured to 3.3 V)

2-3

The VCCA is used

JP10

ADV0/1 – power supply for the ADC module

1-2

The VCORE is used
