Command register
As this register is read, the answer will always contain only zero's.
There are a number of actions that can be activated in the instrument. The value of this
register (when different from zero) will activate one of these actions, as described in
below.
When an action cannot be performed for some reason (wrong state etc.) an exception
is given as reply. When an exception with code 03 or 07 is received the command error
register could be read to get a better error explanation.
