After system bootup, I checked register IOMUXC_SW_MUX_CTL_PAD_GPIO_SD_B1_05, it's FLEXSPIA_DQS, but my code doesn't touch it, it should be GPIO3_IO05 as spec says. So my question is (1) whether ROM code changes this property to FLEXSPIA_DQS? And if I want to change this pin's property to others, and ROM code can use the new property, (2) how can I do? By checking fuse and FlexSPI Configuration Block, no this feature included. Thank you!
