Encryption
The data exchanged between the device and the host during read, write and verify
password commands may be encrypted to ensure data confidentiality.
The issuer may choose to require encryption for a user zone by settings made in the
configuration zone. Any one of four keys may be selected for use with a user zone. In
this case, activation of the encryption mode is required in order to read/write data in the
zone and only encrypted data will be transmitted. Even if not required, the host may
elect to activate encryption provided the proper keys are known.
Supervisor Mode
Enabling this feature allows the holder of one specific password to gain full access to all
eight password sets, including the ability to change passwords.
Modify Forbidden
No write access is allowed in a user zone protected with this feature at any time. The
user zone must be written during device personalization prior to blowing the security
fuses.
Program Only
For a user zone protected by this feature, data within the zone may be changed from a
“1” to a “0”, but never from a “0” to a “1”.
