H616 and newer SoCs feature a 2.5V I/O bias mode in addition to the 1.8V and 3.3V modes. This mode is entered by selecting the 3.3V level and disabling the "withstand function". H616 supports this capability on its main PIO only. A100 supports this capability on both its PIO and R-PIO.

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.
