3.13 APP
3.13.1 Function Overview
The Application Domain is responsible for a variety of application software of the CXD5602. Centered around the
multi core CPU system of the Arm
block such as USB and eMMC, Audio, and Imaging multimedia processing.
The following describes the Application Domain's features.
Depending on the combination of X'tal Oscillator clock frequencies and voltage modes (High Performance
mode/Low Power mode), the performance such as transfer rate varies. This section explains the performances
when 26 MHz is selected as the X'tal Oscillator clock frequency. Overview of APP Maximum Frequency and
sections of each function, for example, for SPI, refer to the Section of SPI (3.10).
