Description
Power Interface
VDDA
Power
Power supply voltage for sensing elements
VDDIO
Power
Digital I/O supply voltage
Controls
PSEL0
Selection pins
These pins determine the signal interface. Note that when the
PSEL0/PSEL1 is not connected, its logic value is 1. When
PSEL0/PSEL1 is connected to GND, its logic value is 0
PSEL1
RESET
Active high reset pin, connect to GND if not used
