Write_Parameter_String
Meaning
With AS-i slaves with profile 7.4, this call can be used to send a parameter string to
the AS-i master that then forwards this to the specified AS-i slave address.
The call transfers a parameter string with a maximum of 220 bytes. The actual
number of parameter bytes to be sent to the AS-i slave is calculated by the AS-i
master from byte 2. The maximum number of parameter bytes is 220.
The remaining information in the string is not evaluated by the AS-i master and is
passed on to the AS-i slave transparently. As long as the string transfer is active,
there is no user/analog data exchange with the addressed AS-i slave.
