Signal Lists
Data Sheet
The following table lists all the external signals in alphabetical order and shows the ball (pin) number on which the
signal appears. Multiplexed signals are shown with the default signal (following reset) not in brackets and the
alternate signal in brackets. Multiplexed signals appear alphabetically multiple times in the list—once for each
signal name on the ball. The page number listed gives the page in “Signal Functional Description” on page 50
where the signals in the indicated interface group begin. In cases where signals in the same interface group (for
example, Ethernet) have different names to distinguish variations in the mode of operation, the names are
separated by a comma with the primary name appearing first. These signals are listed only once, and appear
alphabetically by the primary name.
