Preliminary 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 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 Table 8 on page 57 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. In cases where the signals have the same function but are associated with different
ports (for example, UART), the signals are separated by a slash (/). These signals are listed only once, and appear
alphabetically by the primary mode or primary port name.
