What is the use of the ADC input AIN7? Is it used for any logic internally or just as a voltage measurement?

We are planning for a custom board based on beagle bone black. Is this pin absolutely necessary? Or can we just remove it from circuit?

Thanks in advance.

It's a voltage reference, if you want to tune the values of AIN0->AIN6 in your software..
