Function
Reserved.
Enables privileged software access to the default memory map:
0 = If the MPU is enabled, disables use of the default memory map.
Any memory access to a location not covered by any enabled
region causes a fault.
1 = If the MPU is enabled, enables use of the default memory map
as a background region for privileged software accesses.
When enabled, the background region acts as if it is region number
-1. Any region that is defined and enabled has priority over this
default map.
If the MPU is disabled, the processor ignores this bit.
Enables the operation of MPU during hard fault, NMI, and
FAULTMASK handlers.
When the MPU is enabled:
0 = MPU is disabled during hard fault, NMI, and FAULTMASK
handlers, regardless of the value of the ENABLE bit
1 = the MPU is enabled during hard fault, NMI, and FAULTMASK
handlers.
When the MPU is disabled, if this bit is set to 1 the behavior is
Unpredictable.
Enables the MPU:
0 = MPU disabled
1 = MPU enabled.
