Hi ,
This might be a stupid question, in <<Physical Layer Simplified
Specification Version 2.00>>,there is a command SET_CLR_CARD_
DETECT, as spec discribed Connect[1]/Disconnect[0] the 50 KOhm pull-up
resistor on CD/DAT3 (pin 1) of
the card.
If this command is use to switch the card beteewn the DAT[3] and
CD mode, why i don't see it's being
use in kernel. Under what circumstance we should use this command?
Regards
