2.3 CS-setting on EVA board (default setting)

Make sure to connect CSx1 (USER) on the EVA adapter board (S1 – 1 – USER) to the CS
signal, which is used for the emulation SRAM on the adapter board. This is necessary to set
the transceiver direction to EVA
is performed. Otherwise, the transceiver and the adapter board SRAM write to the DATA
bus, causing corrupted data. Please refer also to section 1.2.
E.g. if CSx1 is routed to the adapter board SRAM (S1 – 1 – EVA), CSx1 must also be
connected to CSx1 (USER) (S1 – 1 –USER).
