WR, BHE and RD selected:
If external data bus is 16 bits wide, data is written to an even
address in external memory space when WRL is held "L".
Data is written to an odd address when WRH is held "L".
Data is read when RD is held "L".
Data is written to external memory space when WR is held "L".
Data in an external memory space is read when RD is held "L".
An odd address is accessed when BHE is held "L".
Select WR, BHE and RD for external 8-bit data bus.
