Description
Sense Inputs: These pins are voltage inputs to the internal A/D
converter. Typically, they are connected to either the outputs of
current sensors or the outputs of resistor dividers (voltage sensors).
Unused pins must be connected to V3P3.
Voltage Reference for the ADC. This pin is left unconnected. Never
use as an external reference.
Crystal Inputs. A 32 kHz crystal should be connected across these
pins. Typically, a 27 pF capacitor is also connected from each pin to
GND. It is important to minimize the capacitance between these
pins. See the crystal manufacturer datasheet for details.
Pin types: P = Power, O = Output, I = Input, I/O = Input/Output
The circuit number denotes the equivalent circuit, as specified under “I/O Equivalent Circuits”.
