We use USB ASSP µPD720231A (USB SATA Bridge) to connect a SATA HDD to a TV SOC's USB 3.0 Port and want to boot them from internal FW, but we wonder about the proper GPIO[3:0] levels for this operation mode. In datasheet it is written to set GPIO]3:0] = 0, but in Reference Board Design Kit - which also does not have an external SPI Flash - GPIO[3:0] = 0x4. Does anyone know about the influence of GPIO2 to the operation modes? in Other
