Register description
LPS001WP
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.
