3.1 Ball Descriptions
This section provides a detailed description of each ball. The signals are arranged in functional groups
according to their associated interface.
The “_N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal
is at a low voltage level. For example, RESET_N indicates that the reset signal is active low. When
“_N” is not present after the signal name, the signal is asserted when at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation, indicates that a signal is inactive.
Note: The buffer type for each signal is indicated in the BUFFER TYPE column of Table 3.1. A
description of the buffer types is provided in Section 3.3.
