9. Predefined settings
9.1. Introduction
This chapter intends to ease the handling of the SX8722 using a set of predefined settings.
These settings are covering a large range of the SX8722 possibilities.
However to avoid too much complexity some features are not handled by these settings.
A more detailed use of the SX8722 can be found under the "advanced configuration" of this document.
This chapter contains predefined command using the masked write mode.
All the settings described in this chapter use the addresses of the 1
table to translate them to other register sets.
