S7G2 attaching an external SRAM 512Kx16 to External Data Bus

Hello

Thank you for your helping in answering my question.

I am looking to connect an external Asynchronous SRAM, 512Kx16, to the R7FS7G27H2A01CBD external Bus.  

I wanted to understand how to connect the Address lines.  So I want to use Single-Write Strobe Mode.  Therefore BC0 and BC1 are used along with WR.

So the SRAM has A0-A18, OE, CS, WE, UB(Upper Byte) and LB(Lower Byte)

I believe and please correct me if I am wrong do I connect the S7G2 A1-A19 to the SRAM A0-A18?

And then connect BC0 to LB and BC1 to UB and then WR to WE?

I have attached a quick block diagram here.
