PRODUCTION DATA.
Table 4-6 lists the recommended connections for unused pins.
Table 4-6 lists two options: 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.
