Interface 2Mb sdram to lpc1788

Hi all.
I have an application where is necessary to interface an
A43L0616B SDRAM to LPC1788 uController.

I have 2 questions about interfacing:

1)The memory chip has only a BA (bank select) pin because
the chip is a 2 bank memory.
This BA pin has to connect to P4[13]/A13 pin (on LPC1788 site)
or to P4[14]/A14 pin?

2)The memory work in RBC (row/bank/collun) mode.
Than it is necessary to take into account 1 or 2 bit,(for
bank select) into shift number used to program mode register
on the memory?.
Pratically:

the memory has 11 row and 8 collun on 2 bank and RBC configuration

to program mode register it's necessary write the following line:

Dummy = *((volatile unsigned long*)(SDRAM_BASE_ADDR | (0x22 << (10))));

or to write the following line:

Dummy = *((volatile unsigned long*)(SDRAM_BASE_ADDR | (0x22 << (11))));

Thank's in advance for your help
