BRDCFG4[USBOSC] and BRDCFG5[SPR] register field of Qixis device is used to control SPI and other IP signal routing. USBOSC: 0= SPI_CLK used as external USB REFCLK input driven with 24.000 MHz. SPI devices are unusable in this mode. 1= SPI_CLK used as SPI clock. SPI devices are usable in this mode. USB block is clocked from internal sources SPR[3:2]: SPI_CS / SDHC_DAT4:7 Routing (schematic net CFG_SPI_ROUTE[3:2]): 00= SDHC/eMMC 8-bit 01= SD Card Rev 2.0/3.0 10= SPI on-board memory 11= TDM Riser / SPI off-board connector. The default value is 00 if an SDCard/eMMC card is selected as the boot device. SPR[1:0]: SPI_SIN/SOUT/SCK Routing (schematic net CFG_SPI_ROUTE[1:0]): 00= SDHC Sync loop 01= TDM Riser / SPI off-board connector. 10= SPI on-board memory. 11= SPI off-board connector. By default, the SPI feature is not available, so we need to configure the above register fields to select the route to the SPI feature.
