TMP102 Temperature Sensor Lib: What does "A0 pin is connected to ground" means?

Hi I am trying to connect ble nano (Nordic nRF51822 SoC) to tmp102 in order to read temp by using the tmp102 project sample

This is the sample imported project:

  1. include "mbed.h"
  2. include "TMP102.h"

TMP102 temperature(p9, p10, 0x90); A0 pin is connected to ground

int main() { while(1) { printf("Temperature: %f\n", temperature.read()); wait(1.0); } }

What does that commented line means?

Tmp102 has not A0 pin and BLE NANO has no A0 pin too.

I am confused

Thanks

Alex
