Some pins may be enabled as general-purpose I/O-port
pins or as alternate functions associated with specific pe-
ripherals or interfaces. These pins may be individually con-
figured as port pins, even when the associated peripheral or
interface is enabled. Table 2 describes the device signals for
the LQFP-128 package. Table 3 describes the device sig-
nals for the LQFP-144 package.
