Signal Lists
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 alternate
signals 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 52 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 mode name appearing first. These signals are listed only once, and appear alphabetically by the
primary mode name.
