16-bit register defined by the card manufacturer
64-bit register defined by the card issuer
Three 8-bit access registers defined by the issuer, one for each user zone (active low)
Table 6-1.
Write Password Enable (WPE): If enabled (WPE = “0”), the user is required to verify the write
password to allow write operations in the user zone. If disabled (WPE = “1”), all write operations
are allowed within the zone. Verification of the write password also allows the read and write
passwords to be changed.
Read Password Enable (RPE): If enabled (RPE = “0”), the user is required to verify either the
read password or write password to allow read operations in the user zone. Read operations ini-
tiated without a verified password will return $00 (or the status of the fuse bits, if either CMA or
PER are still intact). Verification of the write password will always allow read access to the zone.
RPE = “0” and WPE = “1” is allowed but is not recommended.
Authentication Enable (ATE): If enabled (ATE = “0”), a valid authentication sequence is
required for both read and write and must be completed before access is allowed to the user
zone. If disabled (ATE = “1”), authentication is not required for access.
Authentication Only for Write (AOW): If enabled (AOW = “0”), a valid authentication sequence
must be completed before write access is allowed to the user zone. Read access to this zone is
allowed without authentication. This bit is ignored if ATE is enabled.
Password Select (PWS): This bit defines which of the two password sets must be presented to
allow access to the user zone. Each access register may point to a unique password set, or
access registers for multiple zones may point to the same password set. In this case, verification
of a single password will open several zones, combining the zones into a single larger zone.
