The memory space of the C161U is configured in a “Von Neumann” architecture. This
means that code and data are accessed within the same linear address space. All of the
physically separated memory areas, internal RAM, the internal Special Function
Register Areas (SFRs and ESFRs), the address areas for integrated XBUS peripherals
and external memory are mapped into one common address space.
C161U provides a total addressable memory space of 2 MBytes. This address space is
arranged as 32 segments of 64 KBytes each, and each segment is again subdivided into
four data pages of 16 KBytes each (see Figure 8).
