The Static Memory Controller signals pass througth the EBI module where they are multiplexed.
The programmer must first configure the GPIO controller to assign the EBI pins corresponding to
SMC signals to their peripheral function. If I/O lines of the EBI corresponding to SMC
signals are not used by the application, they can be used for other purposes by the GPIO
Controller.
The SMC provides up to 26 address lines, A[25:0]. This allows each chip select line to address
up to 64 Mbytes of memory.
