NV_FREQRNG
0x7
Setting of NV_FREQRNG[8:5] or NV_FREQRNG[12:9] determines
the behavior of eNVM BUSY_B with respect to the AHB Bus
interface clock. It can be used to accommodate various frequencies
of the external interface clock, M3_CLK, or it can be used to
advance or delay the data capture due to variation of read access
time of the NVM core. It sets the number of wait states to match with
the Cortex-M3 or Fabric master operating frequency for read
operations. The small counter in the NVM Controller uses this value
to advance or delay the data capture before sampling data.

NV_FREQRNG[8:5] is used for NVM0 and NV_FREQRNG[12:9] is
used for NVM1.

SW_ENVMREMAPSIZE
0x11
Size of the segment in eNVM which is to be remapped to location
0x00000000. This logically splits eNVM into a number of segments,
each of which may be used to store a different firmware image, for
example. The region sizes are shown in
