Data consistency
Data which contains no contradictions is said to be consistent. The follo-
wing consistency is required here: 1. The high byte and low byte of an
analog value (word consistency), 2. The control/status byte and the corre-
sponding parameter word for accessing the register. The interaction of the
peripherals with the control unit means that data can initially be guaranteed
consistent only within an individual byte: the bits which make up a byte are
read in together, or written out together. Byte-wise consistency is quite
adequate for processing digital signals but is not sufficient for transferring
values longer than eight bits, such as analog values. The various bus sy-
stems guarantee consistency to the required length. It is important to use
the appropriate procedure for importing this consistent data from the ma-
ster bus system to the control unit. You will find a detailed description of
the correct procedure in the User Guide of the appropriate bus system, in
