When there is a change in the configuration of the BMP3xx device, several steps take place. These steps include: 1) Update the OSR settings and check if there was an update 2) Update the ODR settings and check if there was an update 3) Update the IIR settings and check if there was an update 4) Check if there was an update with the following procedure: a) Set sensor to SLEEP mode and after to NORMAL mode to trigger a new measurement. b) Wait the maximum amount possible depending on the OSR settings c) Check the configuration error register if there was an error during the configuration of the sensor. This check is necessary, because there could be a case where the OSR is too high for the requested ODR so either the ODR needs to be slower or the OSR needs to be less. This is something that is checked internally by the sensor when it runs in NORMAL mode. In the BMP58x devices the previous steps are done internally by the sensor. The IIR filter settings do not depend on the OSR or ODR settings, and there is no need to run a check in case they change.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
