PowerPC 440GP Embedded Processor Data Sheet
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
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 41 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.
