In order to avoid restoring of parameters by mistake, restoring is only executed when
a specific signature is written to the appropriat sub-index. The signature is "load".

On reception of the correct signature, the device restores the appropriate default
parameters. If restoring failed, the device responds with abort domain transfer: Error
code 0606 0000h.
If a wrong signature is written, the device refuses to restore the defaults and responds
with abort domain transfer: 0800 0020h.
The default values will be set valid after the device is reset: NMT service RESET
NODE (0x81) for sub-index from 1 to 3, NMT service RESET COMMUNICATION
(0x82) for sub-index 2, or power cycled.
On read access to the appropriate sub-index the device provides information about its
default parameter restoring capability:
