Direct Memory Access (DMA) Introduction

WebSet the burst size for the peripheral DMA module services. For the ADC, the value equals the number of ADC registers used, up to 16. For multichannel buffered serial ports (McBSP), which lack FIFOs, the value is 1. For RAM, the value can range from 1–32. This parameter corresponds to bits 4–0 (BURSTSIZE) in the burst size register (BURST ... WebThe direct memory access (DMA) controller allows a hardware subsystem to access the main memory with minimal monitoring from the central processing unit (CPU).
