TMS320C6747: Can EMIFB be used with only the upper 16 bit data bus

I have a question about how to use EMIFB for C6747.
This EMIFB has a 32-bit data bus, Can it use only the upper 16 bit data bus as SDRAM memory?
In other words, I would like to connect EMB_D[31:16] to SDRAM and use EMB_D[16:0] as GPIO by PINMUXn register configutrations.

Hello H.U,

I am sorry for the late reply. That is not possible. As shown in Figure 19-3 of the TRM, 16-bit SDRAM interfaces must be connected to EMB_D[15:0].
