Card identification mode
Data transfer mode
'Operation
complete'
Transfer command will be accepted. The DAT0 line will remain Low as long as the card
is busy and in the programming stat.
Parameter Set commands (CMD16, CMD32, CMD33) are not allowed while the card is
programming
Read commands are not allowed while the card is programming
Switching another card from the standby to the transfer state (using CMD7) will not
terminate erase and programming operations. The card will switch to the disconnect
state and release the DAT line.
A card in the disconnect state can be reselected using CMD7. The card will then revert
to the programming state and reactivate the busy signaling
Resetting a card (using CMD0 or CMD15) will terminate any pending or ongoing
programming operation. This may result in the loss of card contents. It is up to the host
to prevent possible data loss.
