command failed.
Command not legal for the card
state.
Card internal ECC was applied
but failed to correct the data.
Internal card controller error.
A general or an unknown error
occurred during the operation.
Only partial address space was
erased due to existing WP
blocks.
Sequence or password error
during card lock/unlock
operation.
Card is locked by password.
An erase sequence was cleared
before exciting because an
output of erase sequence
command was received.
The host is trying to change the
ROM section, or is trying to
reserve the copy bit (set as
original) or permanent WP bit
(unprotected) or the CSD
register.
The card enters the idle state
after power up or reset
command. It will exit this state
and become ready upon
completion of this initialization
procedures.
