5.3.2.5. User Mode

The FPGA enters the user mode after exiting the initialization phase. The FPGA user I/O pins are no longer tri-stated in this phase and the configured soft logic in the FPGA becomes active.

The FPGA remains in user mode until the nCONFIG pin is driven low. If the nCONFIG pin is driven low, the FPGA reenters the reset phase. The internal oscillator is disabled in user mode, but is enabled as soon as the nCONFIG pin is driven low.
