Hi, I'm trying to communicate with a SD card on SD bus. now,I read manual LPC23xx in chapter SD/MMC card and Data sheet sandisk SD card.is it enough? Have you got any suggestion to me(or for read)? Have you got any simple piece of software that configure the card. I don't know what to do first? Thank you...

So why did you do it? All those stars didn't just magically appear by themselves - you must have made a conscious decision to type all of them!
Anyhow, have you searched the NXP site for Application Notes, etc, about using the SD card interface?
"
SPI is far less efficient than the "proper" SD bus.
"I see many people use this mode?"
That's because it doesn't rely on a special SD bus interface - any processor with SPI can do it!
Have you looked at the free "simplified" version of the SD Card interface specification? www.sdcard.org/.../sdcard
