Signal Definitions
This section defines the signals and describes the external
interface of the SC3200. 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).
