3.3.2 MIPI-RFFE Mode
When enabled, MIPI-RFFE mode enables the SC4415 to behave as an RFFE Master device.
3.3.2.1 Summary
The RFFE application mode is based on the MIPI-RFFE protocol specification v2.0, designed and maintained by the MIPI
Alliance. This document does not include RFFE protocol specific information such as protocol message formats or
timing information. For further detail about the RFFE specification, refer to
mipi.org .

part(s) of this material may be disclosed, reproduced or used for any purpose other than as

There are two signals required for the RFFE application mode SCLK and SDATA. The SCLK signal is the serial clock signal
driven by the master and the SDATA is the bidirectional data line used to exchange data between master and slave.
The APIO pin functions for RFFE mode are shown in Table 3.3.2.1-1. For more information about the APIO pins refer to
Section 2.5.1.
