Secure-Digital Host Controller (SDHC)

6.17

6.17.1 Overview

The Secure-Digital Host Controller (SDH Controller) includes a DMAC (Direct Memory Access

Controller) unit and a SD unit. The DMAC unit provides a DMA (Direct Memory Access) function

for SD to exchange data between system memory and shared buffer (128 bytes), and the SD unit

controls the interface of SD/SDHC/MMC. The SD HOST controller can support SD/SDHC/MMC

with DMAC to provide a fast data transfer between system memory and cards.

6.17.2 Features



Supports single DMA channel.



Supports hardware Scatter-Gather function.



Using single 128 Bytes shared buffer for data exchange between system memory and

cards.



Interface with DMAC for register read/write and data transfer.



Supports SD/SDHC/MMC card.



The frequency of HCLK should be higher than the frequency of peripheral clock.
