Signal Descriptions
2.1
Introduction
This chapter describes the external signals on the device. It includes an alphabetical listing of signals that
characterizes each signal as an input or output, defines its state at reset, and identifies whether a pull-up
resistor should be used.
NOTE
The terms assertion and negation are used to avoid confusion when dealing
with a mixture of active-low and active-high signals. The term asserted
indicates that a signal is active, independent of the voltage level. The term
negated indicates that a signal is inactive.
Active-low signals, such as SD_SRAS and TA, are indicated with an
overbar.
2.2
Signal Properties Summary
The below table lists the signals grouped by functionality.
NOTE
In this table and throughout this document, a single signal within a group is
designated without square brackets (i.e., A23), while designations for
multiple signals within a group use brackets (i.e., A[23:21]) and is meant to
include all signals within the two bracketed numbers when these numbers
are separated by a colon.
NOTE
The primary functionality of a pin is not necessarily its default functionality.
Pins that are muxed with GPIO default to their GPIO functionality.
