Revision Code: The diagnostic register group contains a
2-bit revision code. If software detection of device revision
is necessary, then contact the factory for details. Otherwise,
the code can be ignored. In all cases, however, the values
of all bits must be used when calculating the packet error
code (PEC) byte on data reads.
Bus Protocols: There are 3 different protocol formats,
depicted in Table 3 through Table 5. Table 2 is the key for
reading the protocol diagrams.
