SPI mode MMC interface registers.
Low Level Multimedia Card Access.
Low level MMC hardware routines, tested on the AT91SAM7X.
These routines support SPI mode only and are required by the basic MMC driver.
* * $Log$ * Revision 1.6 2008/08/11 06:59:13 haraldkipp * BSD types replaced by stdint types (feature request #1282721). * * Revision 1.5 2008/08/06 12:51:01 haraldkipp * Added support for Ethernut 5 (AT91SAM9XE reference design). * * Revision 1.4 2008/02/15 16:59:02 haraldkipp * Spport for AT91SAM7SE512 added. * * Revision 1.3 2008/01/31 09:16:03 haraldkipp * Failed to compile for SAM7S. Added some default settings. * * Revision 1.2 2006/09/05 12:27:55 haraldkipp * Added support for the AT91SAM9260. * * Revision 1.1 2006/07/26 11:20:08 haraldkipp * Added MMC/SD-Card support for AT91SAM7X Evaluation Kit. * * *

NUTDEVICE devAt91SpiMmc0 |
Multimedia card device information structure.
A pointer to this structure must be passed to NutRegisterDevice() to bind this driver to the Nut/OS kernel. An application may then call /verbatim _open("MMC0:", _O_RDWR | _O_BINARY); /endverbatim to mount the first active primary partition with any previously registered file system driver (typically devPhat0).
