For legal accesses, the data interface will forward all accesses to one of two access controllers - the direct access and the indirect access controllers. Assuming DAC has been enabled via the OSPI_CONFIG_REG[7] ENB_DIR_ACC_CTRL_FLD bit, then by default all accesses will be forwarded to this controller. Before any accesses can be forwarded to INDAC, it must first be configured by software. This process is fully explained in Section 12.4.2.4.10, Indirect Controller (INDAC). If DAC is disabled, any incoming access that cannot be forwarded to INDAC will be completed immediately with an error. If DAC is enabled, the same access will be forwarded and serviced by DAC.
