Hi all,


we want to use the EIM for communication between the i.MX processor and an FPGA.

- The accesses are single word, that is why we use the asynchronous mode, single read (SRD=0, SWR=0, APR=0).

- The accesses are of different latency, that is why we want to use DTACK mode and terminate each access on the assertion of the EIM_DTACK signal.


Now I have the following problem:

EIM ignores the DTACK signal, even though DAE is enabled. The length of a read access is always defined by RWSC. Is there any other bit that needs to be configured so that each access is terminated on assertion of EIM_DTACK?


Best regards
