Purpose
With this call, the extended ID1 code of an AS-i slave with address “0” can be
written directly over the AS-i cable. The call is intended for diagnostic purposes
and is not required in the normal master mode. The AS-i master passes on the
extended ID1 code to the AS-i slave without any plausibility check.
