With this command, the four 16 bit channels of an AS-i input slave according to the
slave profile (S-7.3, S-7.4, S-7.5, S-7.A.8, S.A.9, S-7.A.A) can be read.
8.2.1.3 Write 1 16-bit-Slave out Data (WR_7X_OUT)
With this command, the four 16 bit channels of an AS-i output slave according to
the slave profile (S-7.3, S-7.4, S-7.5, S-7.A.8, S.A.9, S-7.A.A) can be written.
A-Slaves map the data on channels 1 and 2.
B-Slaves map the data on channels 3 and 4.
