Notes:
1. If battery is not used, do not connect VBATT.
2. Recommended maximum voltage droop for VCCAUX is 10 mV/ms.
3. The thresholds for Power On Reset are VCCINT > 1.2V, VCCAUX > 2.5V, and VCCO (Bank 4) > 1.5 V.
4. Limit the noise at the power supply to be within 200 mV peak-to-peak.
5. For power bypassing guidelines, see Xilinx Application Note XAPP623.

Notes:
1. Internal pull-up and pull-down resistors guarantee valid logic levels at unconnected input pins. These pull-up and pull-down resistors
do not guarantee valid logic levels when input pins are connected to other circuits.
