1.Is it possible to provide VCCO_4 and VCCO_5 as 3.3V , or is it compulsory to give both these as 2.5V since it is used in configuration and other dedicated configuration pins are driven from VCCAUX which is 2.5V?
2.It is given in Spartan 3 datasheet that certain pins in Banks 4 and 5 can be used as Dual function pins.If we are using these pins in configruation and also as I/O pins how should we provide the connection with these pins.
Is it enough to simply give two connection from each dual fumction pin, if so how will the fpga differentiate between configuration and other signals.Should some switching arrangement be provided for this.?
Does the VCCO_4 and VCCO_5 voltage of the fpga depends on the VCCO and VCCJ of the parallel platform flash PROM interfaced to it?
