Figure 4-1. CP3BT23 Device SIgnals
Some pins may be enabled as general-purpose I/O-port pins or as alternate functions associated with
specific peripherals or interfaces. These pins may be individually configured as port pins, even when the
associated peripheral or interface is enabled. Table 4-1 describes the device signals for the LQFP-128
package. Table 4-2 describes the device signals for the LQFP-144 package.
