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.
The pin types are described below:
Power - these pins are used to supply either VDD or GND to the device.
AIO - Analog Input / Output.
DI - Digital Input.
OD - Open Drain Digital Output.
DIOD - Digital Input / Open Drain Output.
