Interfacing 2 16-bit SDRAM modules with K65 to form 32-bit port

I am trying to interface two 16-bit wide SDRAM modules with a K65 to form a 32-bit port.  I want to use two 2M x16 x4 modules.  I have read through the reference manual and it seems that Table 35-12 meets my criteria (9-column address lines).  However, there are not enough address lines to connect the bank address lines BA0 and BA1.  I don't understand why certain address lines are not used when working with a 32-bit port compared to a 16-bit port.  Can you please help me with the correct hardware connections for a pair of 2M x16 x4 bank SDRAM modules?
