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. Shared signals are shown with the default signal (following reset) not in brackets and the alternate
signal in brackets. Signals that have different functions for different modes with the same function are separated by
commas.
Shared signals appear alphabetically multiple times in the list—once for each signal name on the ball. The Page
column indicates the page within the table “Signal Functional Description” on page 39 on which the signals in the
indicated interface group begin.
