This Figure shows the dual Quad-SPI controller. The controller consists of a legacy linear Quad-SPI controller and the generic Quad-SPI controller. Register control (generic_qspi_sel) set to 1 selects the generic Quad-SPI controller. The shaded units in This Figure are used by both the legacy and generic controllers. The receive capture logic with delay line is shared between both the controllers.
