Re: [lpc2000] LPC214x as an SD device controller

2005-11-03 by Matthias Hertel

Is there a special reason, why you want to do this? 
Using the SPI does not consume that much CPU time, and is quite fast.
As long as you do not want to use SDIO cards, I see no real reason using the 
SD specific transfer modes.
