BOOT bit is used to refresh the content of internal registers stored in the flash memory
block. At the device power up the content of the flash memory block is transferred to the
internal registers related to trimming functions to permit a good behavior of the device itself.
If for any reason the content of trimming registers was changed it is sufficient to use this bit
to restore correct values. When BOOT bit is set to ‘1’ the content of internal flash is copied
