The pin types are described in detail below. All pins labelled with (5V) are 5V tolerant.
Note: For all 5V tolerant pins that require a pull-up resistor, the voltage difference between VDD and
the pull-up voltage must never exceed 3.6V.

DESCRIPTION
Power
DI
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.
Digital Input Output - this pin is used as a digital input / output.
Analog Input / Output - this pin is used as an I/O for analog signals.
DIO

DIOD
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.
OD
DO
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.
Push-pull Digital Output - this pin is used as a digital output and can sink and source current
