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?
