Hi community.


VYBRIDRSERIESEC_Rev_7.PDF p58 "9.5.1 QuadSPI timing" description of "SDR mode"or"DDR mode",

but QSPIFlashROM by the command switches DDR and SDR.


This sheet described in the "SDR mode", "DDR mode" is bit7 of QuadSPI0_MCR register: will be set to "1"  of DDR_EN?


Or refers to the mode of behavior when using the DDRRead/Write command and the SDRRead/Write command?
