Depending on the actualimplementation, there is a delay between the internal clocking in the QuadSPI moduleand the external serial flash device. Refer to the following figure for an overview of thisscheme.Chapter 33 Quad Serial Peripheral Interface (QuadSPI)MWCT101xS Series Reference Manual, Rev. 3, 07/2019NXP Semiconductors 921
