    External Memory Interface


      I intend to use an external RAM with a PSoc3 chip. I find EMI component is available in the standard component library.


      And it has got  ADDRESS , DATA and CONTROL type of I/Os. There are total five(5) I/Os are given without any detail .


      The standard controls required for such interface are  CE,OE and WR.  However, to my surprise I coundn't  find any hint


      about the usages of the 5 Control pins in the component data sheet. So,  when I sit with the hardware design I am not sure about the pin assignments.  And I don't find any example on EMI as well.  Also , I am not sure about the software implementation  of the EMI. Can I get some help on this issue?
