H.2.2. Key Registers (KR) [88RF]
98
POK:
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. The POK bits are only used if Dual Access
Authentication mode has been selected. Any number of PR registers can point to the same key set, allowing multiple
User Zones to use the same key set.
Table 69.
PW:
The Password Set selection bits control the password set assigned to a User Zone. Table 70 shows the coding of
these register bits. Any number of PR registers can point to the same password set, allowing multiple User Zones to
use the same password set.
Table 70.
There is one Key Register for each User Zone in the user memory. The default state of this register is $FF.
Figure 27.
The Key Register bit definitions are shown in Figure 27. Changes to the KR registers are effective immediately.
PK:
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.
