4.5.10 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.
Meaning of bit B:
B = 0 Single AS-i slave or A-slave
B = 1 B-slave
4.5.11 Read parameter (READ_PI: Read_Parameter)
This call returns the current parameter value (actual parameter) of an AS-i slave
sent by the AS-i Master. This value must not be confused with the parameter echo
that is supplied by the AS-i slave as a response to the write_p job.
This command can not be used for a directly reading of an AS-i parameter out of
an AS-i slave.
