Principles of Operation
The next 2 figures show a typical TTP/C node as it is to be deployed in a TTP/C
communication cluster. The circuit example uses the MAX1487 as driver, the host CPU may
be selected by the user and a 29F200 Flash memory. For detailed information the protocol on
application programming refer to the manuals provided by TTTech Computer Technik GmbH.
