Forcing Erase:
In case that the user forgot the password (the PWD content) it is possible to erase all the card data content along with the
PWD content. This operation is called
Forced Erase
.
Select the card (CMD7), if not previously selected already.
Define the block length (CMD16) to 1 byte (8bit card lock/unlock command). Send the card lock/unlock command
with the appropriate data block of one byte on the data line including 16 bit CRC. The data block shall indicate the
mode ERASE (the ERASE bit shall be the only bit set).
If the ERASE bit is not the only bit in the data field then the LOCK_UNLOCK_FAILED error bit will be set in the status reg-
ister and the erase request is rejected.
If the command was accepted then ALL THE CARD CONTENT WILL BE ERASED including the PWD and PWD_LEN
register content and the locked card will get unlocked. In addition, if the card is temporary write protected it will be unpro-
tected (write enabled), the temporary-write-protect bit in the CSD and all Write-Protect-Groups will be cleared.
An attempt to force erase on an unlocked card will fail and LOCK_UNLOCK_FAILED error bit will be set in the status reg-
ister.
If a force erase command is issued on a permanently-write-protect media the command will fail (card stays locked) and
the LOCK_UNLOCK_FAILED error bit will be set in the status register.
The Force Erase time-out is specified in Chapter 6.5.2
