Connections for Unused Signals
Table 18-12 on page 772 shows how to handle signals for functions that are not used in a particular
system implementation for devices that are in a 100-pin LQFP package. Two options are shown in
the table: an acceptable practice and a preferred practice for reduced power consumption and
improved EMC characteristics. If a module is not used in a system, and its inputs are grounded, it
is important that the clock to the module is never enabled by setting the corresponding bit in the
RCGCx register.
