RF Core

The RF Core is the radio peripheral of the CC13x0 family. It is a software configurable, high-performance transceiver that can handle multiple protocol standards. It operates autonomously from the main CPU and is controlled via various commands. Both RF core and CPU are connected by set of »doorbell« registers, interrupt signals and shared memory.

This chapter describes the usage of the RF core and its features from a software developer’s perspective. It provides a more high-level view than the CC13x0 CC26x0 SimpleLink Wireless MCU Technical Reference Manual.
