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].

 

    Address_bus : EIM_AD[15:0]
    Address_bus : EIM_ADDR[25:16]
    Data_bus       :EIM_DATA[23:16] - EIM_EB2_B
    Data_bus       :EIM_DATA[31:24] - EIM_EB3_B

 

[Question]


When we execute the " byte write access" to EIM ,
which data bus is used ?

 

Best Regards,
Koichi Sakagami
