J.3.3. M = 101b Security - Authentication for Write
J.4.
108
When M = 101b Authentication is required for Write access to the User Zone. If Authentication is performed with the
key identified in the PK bits of the Key Register, then Read/Write access is granted to the User Zone. Read-Only
access does not require Authentication or Encryption Activation. A checksum is required for write operations.
88RF PICC behavior is identical to 88SC devices when M = 101b.
The Password Register [88SC]
The Password Registers are used to select the Key Sets for Authentication or Encryption Communication Security. Any
Key Set can be used with any User Zone by programming the Key Register for the User Zone with the appropriate AK
and POK values. One Key Set can be used with any number of User Zones.
Figure 32.
The Authentication Key Set selection bits control the key set assigned to a User Zone for communication security. The
Access Register bits determine the Communication Security mode associated with the AK bits.
Table 84.
The Program-Only Key Set selection bits control the key set assigned to a User Zone for communication security. The
Access Register bits determine the Communication Security mode associated with the POK bits. The POK bits are only
used in Dual Access Authentication mode.
