It inputs a VBUSM * or VBUSP bus, checks the address against the fixed and programmable regions * to see if the access is allowed. If allowed the transfer is passed unmodified * to the output VBUSM or VBUSP bus. If the transfer is illegal (fails the * protection check) then the MPU does not pass the transfer to the output bus * but rather services the transfer internally back to the input bus (to prevent * a hang) returning the fault status to the requestor as well as generating an * interrupt about the fault. * * @subsection References * -# MPU Module Specification. */ #ifndef CSL_MPU_H #define CSL_MPU_H #ifdef __cplusplus extern "C" { #endif #include <ti/csl/soc.h> #include <ti/csl/csl.h> #include <ti/csl/cslr_mpu.h> /** @defgroup CSL_MPU_SYMBOL MPU Symbols Defined @ingroup CSL_MPU_API */ /** @defgroup CSL_MPU_DATASTRUCT MPU Data Structures @ingroup CSL_MPU_API */ /** @defgroup CSL_MPU_FUNCTION MPU Functions @ingroup CSL_MPU_API */ /** @addtogroup CSL_MPU_DATASTRUCT @{ */ /** @brief This is the handle to the MPU Register */ typedef volatile CSL_MpuRegs* CSL_MpuHandle; /** @} */ /* Device specific API which opens the MPU instance and returns a handle used in all subsequent calls */ extern CSL_MpuHandle CSL_MPU_Open (Int32 instNum); #ifdef __cplusplus } #endif #endif /* CSL_MPU_H */
