Universal Serial Interface (USI) supports three types of serial interface such as UART, SPI and I2C. Each protocol works independently. USI can be configured to work as one of these protocols. Define all the USI nodes from the PERIC blocks (USI0-14), in all their possible configurations. These blocks have the TX/RX FIFO depth of 64 bytes.

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 reStructuredText 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.
