5.3.4.2 NEW NFC PIN
The NFC PIN used to protect access to the CONFIGURATION memory area should be changed
from the default value to a user-specific value to avoid unauthorized access to the NFC device
configuration interface.
To do so, first authenticate with the current NFC PIN and then write the new NFC PIN (32-bit
value) to memory.
The new NFC PIN will be applied to the PTM module after pressing & releasing the energy
bow. Until then, the previous NFC PIN will remain valid to unlock the NFC memory.
5.3.4.3 SECURITY LEVEL
The security level register defines what encryption features are used in the radio transmis-
sion. If this register is changed from its default setting via the NFC interface, manual mode
changes via SBC (as described in chapter 3.3) are no longer possible. Both 2 nipple SBC and
3 nipple SBC will still trigger the transmission of a Security Teach-in but in both cases the
mode selected via NFC (If secure mode was selected)
To re-enable the mode change by SBC, a factory reset needs to be executed. The mode
change via NFC remains possible even after first write operation.
The operation and application behaviour of the selected mode is described in chapter 3. Fol-
lowing options can be selected:
0b00000000: Normal mode operation
0b00000001: Secure mode Implicit RLC legacy
0b00000010: Secure mode Explicit RLC (recommended)
0b00000011: Defined by SBC (default). This value cannot be set by NFC write
operation.

5.3.4.4 ALLOW TEACH IN
This flag controls if a Security Teach-in can be triggered by SBC. The Security Teach-in Tel-
egram is described in chapter 3.2.3. The following values can be set:
0b00000000: OFF: SBC will not trigger a secure teach-in telegram
0b00000001: ON (default): SBC will trigger a secure teach-in telegram.
