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. 0x2 CACHEDIS Cache Disable 18 1 PARAM NVM Parameter 0x08 32 NVMP NVM Pages 0 16 read-only PSZ Page Size
