E.1.
User Memory Initialization
The user memory is initialized by using the Set User Zone command to select a User Zone, and writing the initial data
with Write User Zone commands. The data is then verified with Read User Zone commands. Each User Zone is
programmed in this manner.
E.2.
Polling Response and OTP Memory Personalization
After initializing the user memory, the Configuration Memory is programmed with the polling response and OTP data.
Figure 16 shows the polling response registers in blue, OTP memory in green, and access control registers in gray.
The Unique Die Serial Number register is factory programmed and cannot be changed.
There are 27 bytes of OTP memory available for customer use in 88SC PICCs, and 25 bytes in 88RF PICCs; these
registers are shown in green in Figure 16 and Figure 17. See Appendix M for detailed information on configuration of
the polling response registers. See Appendix H for detailed information on configuration of the access control registers.
