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,
