Command data set
There are write-only data sets with more than one entry. With these, you can select which
commands are to be executed.
The first entry is a 16-bit value. You can select the required commands by setting individual
bits to "1". The other bits are ignored. The least significant bit stands for the first command.
The next bit stands for the second command, and so on.
