Descriptions of the Pin functions are as follows:
VDDD: Power supply for the digital section.
VDDA: Power supply for the analog section.
VSSD, VSSA: Ground pins for the digital and analog sections respectively.
VCCD: Regulated digital supply (1.8 V ±5%)
VDD: Power supply to all sections of the chip
VSS: Ground for all sections of the chip
Alternate Pin Functions
Each port pin can be assigned to one of multiple functions; it can, for instance, be an analog I/O, a digital peripheral function, an LCD
pin, or a CapSense pin. The pin assignments are shown in the following table.
