2 or mors bytes
The control or status byte occupies the lowest address of a logical channel.
The corresponding register values are located in the following 2 data bytes
(the BK2000 is an exception to the rule: here, an unused data byte is
inserted after the control or status byte, thus setting the register value to a
word limit).
