Introduction

The Direct Memory Access (DMA) (SiM3U1xx, SiM3C1xx, and SiM3L1xx) and Data Transfer Manager (DTM) (SiM3L1xx) modules are complex data management modules intended to autonomously transfer data between peripherals and memory. These modules can save system power consumption by allowing the core to enter a low power state or process data in parallel to improve performance. This document discusses usage models for these modules.
