3.3 SFP module

The SFP module is based on reconfigurable device pins combined with some local logic to

maximize in-system flexibility of the device in any given application

An SFP can be configured either to be driven as a GPIO or by the local logic block within the

STV0684 (detailed in Figure 3). The functionality and configuration of each SFP is determined and

managed under control of the ST20. Control registers local to each module are mapped into the

processors address space, this leaves the processor to support more demanding, computational

intensive tasks.
