External Memory Interface
Overview
With all the features that the External Memory Interface provides, it is well suited to operate as
an interface to memory devices such as external SRAM and Flash, and peripherals such as
LCD-display, A/D, and D/A. The main features are:
When the eXternal MEMory (XMEM) is enabled, address space outside the internal SRAM
becomes available using the dedicated external memory pins (see

tion is shown in
Figure 7-4.
Note:
• Four different wait-state settings (Including no wait-state).
• Independent wait-state setting for different external memory sectors (configurable sector
• The number of bits dedicated to address high byte is selectable.
• Bus Keepers on data lines to minimize current consumption (optional).
