5.5 Nonvolatile Latches (NVLs)
PSoC has a 4-byte array of nonvolatile latches (NVLs) that are used to configure the device at reset. The NVL register map is shown
in
Table 5-2. Device Configuration NVL Register Map
The details for individual fields and their factory default settings are shown in
Table 5-3. Fields and Factory Default Settings
Although PSoC Creator provides support for modifying the device configuration NVLs, the number of NVL erase / write cycles is limited
