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.
