This register is used by the QSPI controller to determine whether incoming memory accesses on the QSPI AHB memory window are meant to access the SRAM FIFO or to be interpreted as direct access requests. When the incoming access is between indaddrtrig and indaddrtrig+15, the access is directed towards SRAM FIFO; otherwise it is interpreted as a direct access request. Note that it does not matter which address in the indaddrtrig to indaddrtrig+15 interval is accessed, any access is treated the same and will be directed to SRAM FIFO. When direct mode is not used, the recommended procedure is to leave indaddrtrig as 0, and use the base of the AHB memory window to access the SRAM FIFO. |
