Implement .get_state to read-out the current hardware state. The hardware readout may return slightly different values than those that were set in apply due to the limited range of possible prescale and counter register values. Also note that although the datasheet mentions 200 Hz as default frequency when using the internal 25 MHz oscillator, the calculated period from the default prescaler register setting of 30 is 5079040ns.

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.
