Functional Description
I/O Lines
External Memory Interface
External Memory Mapping
The pins used for interfacing the Static Memory Controller may be multiplexed with the PIO
lines. The programmer must first program the PIO controller to assign the Static Memory Con-
troller pins to their peripheral function. If I/O lines of the Static Memory Controller are not used by
the application, they can be used for other purposes by the PIO Controller.
The memory map is defined by hardware and associates the internal 32-bit address space with
the external 23-bit address bus. Note that A[22:0] is only significant for 8-bit memory. A[22:1] is
used for 16-bit memory. If the physical memory device is smaller than the page size, it wraps
around and appears to be repeated within the page. The SMC correctly handles any valid
access to the memory device within the page. See
