5.2. Active Serial (AS) x4 Configuration Mode
The AS x4 configuration mode can be set to either fast or normal mode. When the AS x4 mode is enabled, the FPGA configures itself after power-on with the programming file stored within the QSPI flash (U9) connected directly to the FPGA SDM interface. In this mode, the FPGA downloads its programming bitstream directly from the QSPI flash device. This is the default configuration mode for the board shipped from the factory.
