Input
Input pins for device address selection. To configure a device address,
these pins should be connected to the VCC or VSS of the device.

SDA
I/O
Bi-directional data pin for the I2C-bus serial data interface. Schmitt
trigger input and open-drain output. An external pull-up resistor must
be connected to VCC. Typical values for this pull-up resistor are 4.7 kW
(100 kHz) and 1 kW (400 kHz).
