The MCR[LPMACK] read-only bit indicates that FlexCAN is in a lower-power mode (Disabled mode, Doze mode, Stop mode). The CPU can poll this bit to know when FlexCAN has actually entered low power mode. The low power enter/exit acknowledgment helper will reduce code duplication for disabled mode, doze mode and stop mode.

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.
