An I/O bank can simultaneously support any number of input signals with different I/O standard assignments if the I/O standards support the VCCIO level of the I/O bank.

For output signals, a single I/O bank supports non-voltage-referenced output signals that drive at the same voltage as VCCIO. Because an I/O bank can only have one VCCIO value, it can only drive out the value for non-voltage-referenced signals.

For example, an I/O bank with a 2.5 V VCCIO setting can support 2.5 V standard inputs and outputs, and 3.0 V LVCMOS inputs only.
