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
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).
