SD/MMC using MCI Example for EVK1104 Documentation

Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the SD/MMC driver in MCI mode.
It also comes with an example of the usage of this driver.

This file gives an example of using the SD/MMC card driver. If a SD/MMC card is detected, the main() function reads data from SD/MMC to internal RAM. It displays on RS232 the first sector from SD/MMC physical sector number 1.
