iMX7D how can I configurate the EIM_LBA_B measured form low active to high active?

Question asked by Manfred Hauser on Dec 18, 2017

We have to access an external SRAM with a 16Bit multiplexed Bus.

I have configurated all the Pins for external RAM and defined the EIM Registers . The Address vaild signal EIM_LBA_B now is low active.

How can I change EIM_LBA_B to high active? In my hardware is a address latch (ALE) high active, because this I needed the signal "inverted". Is there a possibility?

I configurated EIM_CS0GCR1, EIM_CS0GCR2,  EIM_CS0RD1,  EIM_CS0RD2.

best regards
