"K" – Kill, Lock, Access Descriptors
There are five sections of memory that can be each individually locked:
1. Kill password
2. Access password
3. EPC memory
4. TID memory
5. User memory
The Gen2 protocol specification referenced above describes the data fields associated with the
Lock command. The data is a 20 bit number consisting of a 10 bit Mask field and an associated
10 bit action field. In the Insight reader, we use this number with the KL command lock
descriptor to control the Locking behavior. The meaning of each bit is described in the table
below.
