As per the RZ/G2L users hardware manual (Rev.1.20 Sep, 2022), section 23.3.7 Serial Data Transmission (Asynchronous Mode) it is mentioned that the TE (transmit enable) must be set after setting TIE (transmit interrupt enable) or these 2 bits are set to 1 simultaneously by a single instruction. So set these 2 bits in single instruction.

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.
