APPLICATION NOTE:
For the 5V tolerant pins that have a pull-up resistor (SMCLK, SMDATA, THERM, and
ALERT), the voltage difference between VDD and the pull-up voltage must never exceed
3.6V.

DESCRIPTION
This pin is used to supply power or ground to the device.
Analog Input / Output -This pin is used as an I/O for analog signals.
Digital Input - This pin is used as a digital input. This pin is 5V tolerant.
Digital Input / Open Drain Output - This pin is used as a digital I/O. When it is used as
an output, it is open drain and requires a pull-up resistor. This pin is 5V tolerant.
Open Drain Digital Output - This pin is used as a digital output. It is open drain and
requires a pull-up resistor. This pin is 5V tolerant.
