DATASHEET
This pin is used to supply power or ground to the device.
Digital Input - this pin is used as a digital input. This pin is
5V tolerant.
Analog Input - this pin is used as an input for analog
signals.
Analog Output - this pin is used as an output for analog
signals.
Analog Input / Output - this pin is used as an I/O for analog
signals.
Push / Pull Digital Output - this pin is used as a digital
output. It can both source and sink current.
Digital Input / Open Drain Output this pin is used as an
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.
