AS-i 3.0 Command Interface
Commands of the Command Interface
4.6.10 Write parameter (WRITE_P)
The AS-i slave parameter value transferred with the command is passed on to the
addressed AS-i slave.
The parameter is stored in the AS-i Master only temporarily and is not stored as a
configured parameter in the EEPROM!
The AS-i slave transfers its current parameter value in the response (parameter
echo). This can deviate from the value that has just been written according to the
AS-i master specification.
