What are the voltage requirements for the voltage sensor pins VSIGP and VSIGN, when used in unipolar input mode in Arria 10 devices?

Description

When the voltage sensor is used in unipolar input mode in Arria® 10 devices, the VSIGP input must be driven by an external analog signal. The VSIGN pin must be connected to a local ground or a common mode signal.

The voltage on the VSIGP pin when measured with respect to the VSIGN pin must always be positive.
