2.4.2. Static memory interface

The SMI is a 32-bit External Bus Interface (EBI) that can connect up to four 256MB banks of zero to four wait state memory to the EASY microcontroller. However, the number of wait states is set as a constant in the HDL (before synthesis), and is set for all four banks. The example SMI also supports test signals from the TIC. These override the normal operation of the SMI during system test, and directly control the tristate drivers on the XD bus.
