Chapter 5 External Bus Interface (S12XEBIV4)
5.4
This section describes the functions of the external bus interface. The availability of external signals and
functions in relation to the operating mode is initially summarized and described in more detail in separate
sub-sections.
5.4.1
A summary of the external bus interface functions for each operating mode is shown in
