A.4.2.5 Restricting USER2_CONFIGURATION_OPTIONS
USER1 can restrict the configuration options that are available to USER2. This allows USER1
(for instance an OEM) to pre-configure certain parameters (for instance the radio protocol)
and prevent USER2 (for instance an installer) from changing those. To do so, USER1 has to
update USER2_CONFIGURATION_OPTIONS with the desired restrictions.
Consider the example of USER1 wanting to prevent USER2 from changing the radio configu-
ration register RADIO_CONFIG so that USER2 cannot change the radio protocol from BLE to
ZGP or vice versa.
To do so, USER1 has to modify the USER2_CONFIGURATION_OPTIONS register described
in Chapter 5.6.15 such that RADIO_CONFIG cannot be changed by USER2. The required
change (via the shadow register in the NEW CONFIGURATION area) is shown below for ref-
erence (marked in red).
