MMC modes

Jan 06, 2005 0 Replies

Hi all,



I hope someone can help me out with a simple question about interfacing to an MMC/SD card.



I wish to talk to card via MMC mode. Does that mean that pin 1 of the MMC card should be driven with a logic high signal, or should be it be left floating?



I understand that by driving a logic low signal onto pin 1 of the MMC card will select it and put it into SPI mode.



Can anyone confirm that?



thanks,
