MultiMediaCard^TM
‘1’ = protected
protected block.
25 CARD_IS_LOCKED SX ‘0’ = card unlocked When set, signals that the card is locked by A
‘1’ = card locked
the host.
24 LOCK_UNLOCK_FA ERX ‘0’ = no error
Set when a sequence or password error C
ILED
‘1’ = error
has been detected in lock/unlock card
command or it there was an attempt to
access a locked card.
23 COM_CRC_ERROR ER ‘0’ = no error
The CRC check of the previous command B
‘1’ = error
failed.
22 ILLEGAL_COMMAN ER ‘0’ = no error
Command not legal for the current state
B
D
‘1’ = error
21 CARD_ECC_FAILE EX ‘0’ = success
Card internal ECC was applied but the C
D
‘1’ = failure
correction of data is failed.
19 ERROR
ERX ‘0’ = no error
A general or an unknown error occurred C
‘1’ = error
during the operation.
18 UNDERRUN
EX ‘0’ = no error
The card could not sustain data transfer in C
‘1’ = error
stream read mode.
17 OVERRUN
EX ‘0’ = no error
The card could not sustain data C
‘1’ = error
programming in stream write mode.
16 CID_OVERWRITE/ ERX ‘0’ = no error
can be either one of the following errors : C
CSD_OVERWRIT
‘1’ = error
- The CID register is already written and
E
can not be overwritten.
- The read only section of the CSD does
not match the card content.
- An attempt to reversecopy (set as original)
or permanent WP (unprotect) bits was
done.
15 WP_ERASE_SKIP SX ‘0’ = not protected Only partial address space was erased due C
‘1’ = protected
to existing WP blocks.
14 CARD_ECC_DISAB SX

13 ERASE_RESET
SR
‘0’ = enabled
‘1’ = disabled
‘0’ = cleared
‘1’ = set
12:9 CURRENT_STATE SX
8 EADY_FOR_DATA SX
7:6 reserved
5 APP_CMD
SR
0 = idle
1 = ready
2 = ident
3 = stby
4 = tran
5 = data
6 = rcv
7 = prg
8 = dis
9–15 = reserved
‘0’ = not ready
‘1’ = ready
Permanently 0
‘0’ = disabled
‘1’ = enabled
4 reserved
Permanently 0
3:2 reserved for application specific commands
1:0 reserved for manufacturer test mode
The command has been executed without A
using the internal ECC.
An erase sequence was cleared before C
executing because an out of erase
sequence command was received
Current state of the card.
B
corresponds to buffer empty signaling on A
the bus
The card will expect ACMD or indication C
that the command has been interpreted
as ACMD.
