MPU Permission Select Register - MPUPSRn
Table 6-1.
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.

• Size - Size of the protection region. The possible sizes are shown in
• V - Valid. Set if the protection region is valid, cleared otherwise. This bit is written to 0 by a
reset. The region is not considered in the protection testing if the V bit is cleared.
