8.3.2.22 Set Auto Address Enable (SET_AAE)
This call can enable or disable the "automatic address programming" function.
The AUTO_ADDR_ENABLE bit is stored permanently; in other words, it is retai-
ned after a warm/hot restart on the AS-i master.
When the AS-i slave address is changed, the AS-i slave is not reset,
in other words, the output data of the AS-i slave are retained until
new data are received at the new address.
