SPI FPGA pins D02 and D03 have no pull-ups on the module, so with PUDC=High option, those pins are floating if there are no pull-ups on baseboard. As those pins have SPI RESET function when Quad mode is not enabled, it is mandatory to either add pull-ups on user baseboard or program the Quad Enable bit in Flash nonvolatile status register. |
