Does EIM support the old Intel Multiplex operation mode

I have a device that I would like to connect to my iMX6-DL via a parallel interface using the EIM module. This device is rather old and supports 10 MHz interfaces using "Motorola", "Intel", or "Intel Multiplexed" pin schema.


To reduce pin count, I would like to use the "Intel Multiplexed" mode. I see that the EIM supports multiplexed address/data but do not see anything like ALE functionality in the EIM description. (The EIM_LBA is active low and I do not see it deasserting before CS assertion.)


Does anyone know if the EIM can support this functionality? If so, is there a data sheet that describes the timing of this interface?
