About the behavior of the CS assertion period with the DTACK mode for EIM

Dear all,

 

We have a question about the CS assertion period with the DTACK mode for EIM.

We use i.MX6Solo.

 

We set EIM as follows.

RWSC=28clk / RCSA=0clk / RSCN=3clk / DAP=0(Active H) / DAPS=0(3clk)

1clk=10ns

 

When DTACK signal becomes active after CS was asserted, CS assertion time is extended for waiting time of DTACK.

 

Is this behavior right?
