If the operation mode is non-zero and an external reference voltage is set, first the operation mode is written to the advanced configuration register, followed by the externel reference enable bit, resetting the configuration mode to 0. To fix this, first compose the value of the advanced configuration register based on the configuration mode and the external reference voltage. The advanced configuration register is then written to the device, if it is different from the default register value (0x0).

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 Restructured Text 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.
