5.1.3.1 SlotLock
The Slot Lock mode of the Lock command is used to individually lock
slots. Any slot that has the Lockable bit set and has not previously been slot-locked
can be locked to prevent any further updates. This process is not reversible. Once a
slot has been locked, it is permanently locked. In this mode of operation, the Summary
CRC and Data fields are ignored.
For the ATECC608B-TNGLoRaWAN, the following individual slots may be locked: Slots 8, 10 and 14.
