I am using the TMP112 I2C temperature sensor and noticed that you can choose between 4 slave addresses by connecting the A0 pin to V+, GND, SCL, or SDA.
How does the sensor tell between SCL, SDA, and V+?
It makes sense that V+ and GND can set the LSB of the slave address, but I am curious as to how the other two connections work.
Here's the link to the datasheet: http://www.ti.com/lit/ds/symlink/tmp112.pdf
I am using this sensor in an undergraduate senior project and am just curious about how this works. The answer won't affect my use of the sensor; I am just curious.
Side note: this is my first question on StackExchange so any feedback on improving my questions is appreciated.
