The EMIF uses the PSOC I/O to provide 24 bit address, 16 bit data and control to external memory.

   

1. Is it possible to address larger memories? The PSOC5 memory map allows for 1 GB of external memory. Can the additional address bits be accessed and used to interface with larger memory devices?

   

2. Can code be executed out of this memory?

Code can be executed from EMIF in PsoC5LP, but only with 16-bit external memories.

Datasheet says:

   

1) No, perhaps with quite a bit of UDB magic, but I doubt it

   

2) Yes, code can be executed.  13.3.1 PSoC 5LP Memory Map ... Note that code can be executed from the code,
SRAM, and external RAM regions.
