SET/
Assigns relative address to
R6 (SDIO)
SEND_RELATIVE_AD
DR
the card.
-
SET_DSR
Programs the DSR of all
cards.
R4
IO_SEND_OP_COND Asks all SDIO cards in idle
state to send their operation
conditions register contents in
the response on the CMD
line.
R1
SWITCH_FUNC
Checks switch ability (mode
0) and switch card function
(mode 1). Refer to "SD
Physical Specification V1.1"
for more details.
R1b
SWITCH
Switches the mode of
operation of the selected card
or modifies the EXT_CSD
registers. Refer to "The
MultiMediaCard System
Specification Version 4.0
Final draft 2" for more details.
R1b
SELECT/
Toggles a card between the
DESELECT_CARD
stand-by and transfer states
