Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Disables folding of IT instruction.
Disables write buffer use during default memory map accesses. This
causes all bus faults to be precise bus faults but decreases the
performance of the processor because the stores to memory have to
complete before the next instruction can be executed.
Disables interruption of multi-cycle instructions. This increases the
interrupt latency of the processor becuase LDM/STM completes
before interrupt stacking occurs.
