The

driver tries to avoid unnecessary station address reprogramming for
controllers that use eFuse to store station address.
The number of times that eFuse can be safely reprogrammed is 16 at
most.
In addition, there is no way to restore factory default station
address once station address is reprogrammed via eFuse.
It is highly recommended not to reprogram station address and
it is responsibility of administrator to store original station
address into a safe place when station address should be changed.
