The single-port XR21B1411 is similar to the XR21B142X type but uses 12-bit registers and 16-bit register addresses, the register requests are different and are directed at the device rather than interface, and 5 and 6-bit words are not supported. The register layout is very similar to XR21B142X except that most registers are offset by 0xc00 (corresponding to a channel index of 12 in the MSB of wIndex). As the device is single-port so that the derived channel index is 0, the current register accessors can be reused after simply changing the address width.

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.
