A mechanical selector on EVM6437?

Anonymous

Hi All,

 

I would like to ask a question on EVM6437 storage chip connection.

 

 

 

In the schematics we can actually see that both the NOR flash and SRAM are connected to EMIF in memory mapping CS2 (overline). To avoid address contention, only one device at a time can be enabled. So is this JP2 a mechanical switch/selector so that the user can pick the plastic cap (with wire conductor inside) out and connect it to one of the four connection, to allow manual selection of EMIF device?

 

 

 

Thanks,

Zheng
