The PCA9685 supports listening to 1 or more alternative I2C chip addresses for some special features that this driver does not support. By default the LED ALLCALL address is active (default 0x70), which causes this chip to respond to address 0x70 in addition to its main address (0x41). This is not desireable if there is another device on the same bus that uses this address (like a TMP103 for example). Since this feature is not supported by this driver, it is best to disable these addresses in the chip to avoid unsuspected bus collisions.

README
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.
