iMX6DQ : EIM byte access on 16bit Data-bus

[koichisakagami]

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

Hello,

For even bytes - EB2 is asserted ; for odd bytes - EB3.

Have a great day,
Yuri
