Description: PXA27x的MMC/SD IO控制器在访问PXA27x处理器的软件与MMC存储堆和支持MMC、SD及SDIO通信协议之间充当联结作用。PXA27x的MMC控制器协议规范遵守多媒体卡系统规范V3.2（MultiMediaCard System Specification Version 3.2)；SD控制器支持一个基于SD存储卡规范V1.01（SD Memory Card Specification Version 1.01）SD卡或基于SDIO卡规范V1.0( SDIO Card pecification Version 1.0)。MMC/SD/SDIO控制器采用标准的MMC传输协议或串行通信接口SPI协议模式。访问PXA27x的软件使用MMC传输协议或SPI模式作为与MMC控制器通信的协议。-PXA27x the MMC/SD/SDIO controller in the PXA27x processor to access the software and MMC memory heap and support MMC, SD and SDIO act as a link between the role of communication protocols. PXA27x MMC controller protocol specification to comply with the Multimedia Card System Specification V3.2 (MultiMediaCard System Specification Version 3.2) SD controller supports an SD memory card standard based on V1.01 (SD Memory Card Specification Version 1.01) SD card or SDIO card based on Specification V1.0 (SDIO Card pecification Version 1.0). MMC/SD/SDIO MMC controller in a standard transmission protocol or serial communication interface SPI protocol mode. Software used to access PXA27x MMC or SPI mode of transport protocol as communication protocol with the MMC controller. Platform: |

Description: Designing and programming a USB mass-storage device or embedded USB
host involves a variety of interfaces, protocols, and structures.
Every USB mass-storage device must support two interfaces:
• A USB device interface to enable the device to communicate with a PC
or other USB host.
• An interface between the device’s microcontroller or other CPU and the
storage media. Flash-memory cards typically use the Serial Peripheral
Interface (SPI), MultiMediaCard bus, SD-Card bus, or a bus derived
from the ATA interface or PC-Card bus. Hard drives typically use the
ATA parallel interface.
A USB mass-storage device must implement these protocols and structures:
• Generic USB protocol. Every USB device must respond to requests sent
by the USB host and other events on the bus.
