23 Device does not do erase-on-write (erase-on-program, auto-erase
24 on write) and requires explicit erase procedure to be programmed
26 some other value, as program can only change bits from erased-value
28 All pure Flash devices are evolution of EEPROM where erase has
29 been separated from write, EEPROM has erase-on-write, giving
30 it advantage of higher write speeds at a cost of larger erase block.
31 Note that explicit-erase capability does not warrants that
32 write without erase is not allowed, taking the above restrictions,
34 erase.

30 Explicit erase (non-erase-on-write) Flash, which is device that requires erase
31 to erase-value prior to write as it only allows to change bits from erase-value
45 …If selected, writing to a non-erased program unit will succeed, otherwise, it will return an error.
46 Keep in mind that write operations can only change value of a bit from erase-value to the
50 but only change from erase-value to opposite will be registered.

55 This allows interrupting flash erase between operations
57 This feature may also be used for better syncing flash erase
62 int "Partial erase timeout in MS"
66 This is maximum time, in ms, that NVMC will use to erase part
78 to the flash erase and write operations timeout. The base for
