Command description
resets all cards to Idle State
checks for cards not supporting the full
range of 2.0 V to 3.6 V. After receiving
CMD1 the card sends an R3 response
(refer to Chapter “Responses”).
asks all cards in ready state to send
their CID*
assigns relative address to the card in
identification state.
programs the DSR of all cards in
stand-by state.
command toggles a card between the
standby and transfer states or between
the programming and disconnect state.
In both cases the card is selected by
its own relative address while
deselecting the prior selected card.
Address 0 deselects all.
asks the addressed card to send its
card-specific data (CSD)*
line.
asks the addressed card to send its
card identification (CID) on CMD- line.
reads data stream from the card,
starting at the given address, until a
STOP_TRANSMISSION follows.
forces the card to stop transmission
Asks the addressed card to send its
status register.
Sets the card to inactive state in order
to protect the card stack against
communications breakdowns.
