to restore the correct values. When the BOOT bit is set to ‘1’ the content of internal flash is

copied inside the corresponding internal registers and is used to calibrate the device. These

values are factory trimmed and they are different for every device. They permit a good

behavior of the device and normally they do not have to be changed. At the end of the boot

process the BOOT bit is set again to ‘0’.

The BOOT bit takes effect after one ODR clock cycle.
