Functional Restrictions
B.4.7 High-Speed USB Host Subsystem
The third HSUSB host port (port 3) featured by the HSUSB host controller is not accessible outside the
devices in the CUS package.
All die pads that are not connected to a ball on a CUS package are shown highlighted in Section B.5 ,
Control Module Pad Multiplexing Register Fields. The same section also provides information about the
multiplexing capabilities of each device pad (that is, the possible signals that can be assigned to each
device pad).
B.4.8 General-Purpose Interface
Table B-6 describes the GPIO channels for the devices in the CUS package. The nonfunctional GPIO
channels in the CUS package are highlighted in orange.
