Hi !


K82 have PPB bus with esome contol registers and MMCAU.


Private peripheral (PPB) bus The PPB provides access to these modules: • ARM modules such as the NVIC, ETM, ITM, DWT, FBP, and ROM table • Freescale Miscellaneous Control Module (MCM) • Memory-Mapped Cryptographic Acceleration Unit (MMCAU)


I have configured MPU where access to MMCAU is enabled in UserMode,

e,g whole peripheral area  0x40000000 - 0xFFFFFFFF have RW rights.


But any read access to MMCAU range 0xE0081000 - ...1FFFF generate BusFault.


AIPS is also dosn't have any register for enable access to MMCAU.


How I can configure K82 blocks for have access to MMCAU address rang in UserMode ?
