MPU Permission Select Register - MPUPSRn
Table 7-1.
A MPU Permission Select register is implemented for each of the 8 protection regions. Each
MPUPSR register divides the protection region into 16 subregions. The bitfields in MPUPSR
specifies whether each subregion has access permissions as specified by the region entry in
either MPUAPRA or MPUAPRB.
