Dear community,


We have a question about EIM byte access.


The EIM is configured for 16-bit Non Multiplexed Address/Data mode communication [ DSZ=010, MUM=0].

 ( Single Asynchronous mode Access)

    Address_bus : EIM_ADDR[25:0]
    Data_bus       :EIM_DATA[23:16] - EIM_EB2_B
    Data_bus       :EIM_DATA[31:24] - EIM_EB3_B


I set 'AUS=1' of EIM_CSnGCR1.

also, I  set 'MUM=0' of EIM_CSnGCR1.



When we execute the " byte read(even/odd) access" to EIM at non-shift address mode,


Address[25:1] signal runs well(High or Low), but

Address0 no change(Always Low).
