1. When not specified VCCIO can be set anywhere in the valid operating range.
2. VCCIO needed for on-chip termination to VCCIO/2 or VCCIO only. VCCIO is not specified for off-chip termination or VTT termination.
3. All ratioed input buffers and dedicated pin input buffers include hysteresis with a typical value of 50mV.
