3.0Signal Definitions; Figure 3-1. Signal Groups - AMD Geode SC1200 Data Book

Signal Definitions
This section defines the signals and describes the external
interface of the SC1200/SC1201 processor. Figure 2-1
shows the signals organized by their functional groups.
Where signals are multiplexed, the default signal name is
System
Interface
Memory
Interface
ACCESS.bus
Interface
Parallel Port/
TFT/VOP Interface
Video Port
Interface
Note: Straps are not the default signal, shown with system signals for reader convenience. However, also listed in figure with the
appropriate functional group.
AMD Geode™ SC1200/SC1201 Processor Data Book
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., cycle multiplexed).
