Signal Definitions
3.1
As illustrated in Figure 3-1 on page 23, the Geode CS5535
companion device is configurable. Boot options and regis-
ter programming are used to set various modes of opera-
tion and specific signals on specific balls.
This section describes the ball assignments and interface
options:

The “#” symbol at the end of a signal name indicates that the active, or asserted state occurs when
the signal is at a low voltage level. When “#” is not present after the signal name, the signal is asserted
when at a high voltage level.
A “/” in a signal name indicates the function is always enabled (i.e., time multiplexed - available when
needed).
A “+” in a signal name indicates the function is available on the ball, but that either strapping options or
register programming is required to select the desired function.
