Signal Definitions
This section defines the signals and describes the external
interface of the AMD Geode™ CS5535 companion device.
Signal multiplexing has been utilized to a high degree. For
example, the IDE and Flash interfaces are multiplexed on
the same balls. Configuration is dependent upon the boot
options selected (see Table 3-5 "Boot Options Selection"
on page 34). If Flash is selected, the user has the option of
using NOR and/or NAND Flash devices.

The GPIOs are configurable (e.g., any GPIO input can be
mapped to an interrupt, ASMI, or PME). Figure 3-1 shows
the signals organized in typical functional groups - not all
possible multiplexing is shown.
Where signals are multiplexed, the primary signal name is
listed first and is separated by a plus sign (+). A slash (/) in
a signal name means that the function is always enabled
and available (i.e., time multiplexed).
