I know the IC@s on the 1002 are bus switching devices, why are they needed? What do they do please?
They switch certain signals between two configurations, based on the jumper settings on the STK1002. For example, the second ethernet interface shares some signals with the LCD interface, so there's a switch that controls whether those signals are routed to the ethernet PHY or the LCD panel.
You won't need them if you're doing a custom design. They're only there to make the STK1000/STK1002 combo more flexible. |
