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 ATECC608A-TNGLoRaWAN, the following individual slots may be locked: Slots 8, 10 and 14.
