The Key Register [88RF]
The Key Registers are used to select the Key Sets for Authentication or Encryption Communication Security on 88RF
PICCs. Any Key Set can be used with any User Zone by programming the Key Register for the User Zone with the
appropriate PK and ROK values. One Key Set can be used with any number of User Zones.
Figure 37.
The Primary Key Set selection bits control the key set assigned to a User Zone for communication security. The
Access Register M bits determine the Communication Security mode associated with the PK bits.
Table 97.
The Read-Only Key Set selection bits control the key set assigned to a User Zone for communication security. The
Access Register M bits determine the Communication Security mode associated with the ROK bits. For some
Communication Security modes the ROK register bits are not used.
