Preliminary
3.1
The memory space of the XC226x is configured in a von Neumann architecture, which
means that all internal and external resources, such as code memory, data memory,
registers and I/O ports, are organized within the same linear address space.

1) The areas marked with “<” are slightly smaller than indicated, see column “Notes”.
2) One 4-Kbyte sector reserved for internal use.
3) Several pipeline optimizations are not active within the external IO area. This is necessary to control external
