Notes:
1. Configuration data is retained even if VCCO drops to 0V.
2. VBATT is required only when using bitstream encryption. If battery is not used, connect VBATT to either ground or VCCAUX.
3. For 3.3V I/O operation, refer to the Virtex-4 FPGA User Guide.
4. Includes VCCO of 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V.
5. The configuration output supply voltage VCC_CONFIG is also known as VCCO_0.
