NO_MISS_PENALTY
The NVM Controller (cache system) does not insert wait states on a cache miss. Gives the best system performance.
0x0
LOW_POWER
Reduces power consumption of the cache system, but inserts a wait state each time there is a cache miss. This mode may not be relevant if CPU performance is required, as the application will be stalled and may lead to increase run time.
0x1
DETERMINISTIC
The cache system ensures that a cache hit or miss takes the same amount of time, determined by the number of programmed flash wait states. This mode can be used for real-time applications that require deterministic execution timings.
