Lpc2000

The LPC22xx have Byte Lane Select lines (BLS0 to BLS3) that you can use 
for this. You don't need the WAIT pin, because you can configure the 
External Memory Controller (EMC) with wait states.

I found figure 11 on page 61 and the pin descriptions on page 57 of the 
UM_LPC21XX_LPC22XX_2.pdf explained most of how the external memory 
controller (EMC) works.
