BIAS Bias

I/O Bias (BIAS). When tied to +5V via a 1 KΩ
resistor, the BIAS input is used to bias the wells in
the input and I/O pads so that the pads can tolerate
5V on their inputs without forward biasing internal
ESD protection devices. When BIAS is tied to
+3.3V, the inputs and bi-directional inputs will only
tolerate 3.3V level inputs.
