Signal Definitions3

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).
