ZNEO MEMORY LAYOUT
The external Flash memory on the ZNEO development kit board
has a 16-bit bus. All writes to Flash memory must be 16 bits at
even addresses only. Attempts to write 1 byte will result in the
byte being replicated on both the upper and lower bytes of the 16-
bit bus.
The ZNEO CPU has a unique memory architecture with a unified 24-bit
physical address space, which is partitioned into several distinct memory
areas. In terms of physical memory spaces, the overall address space can
include the following:
•
•
•
•
The internal spaces listed above are always present in ZNEO devices,
while the external space is optional. Every address space is defined as a
specific range of addresses located at a given place in the framework of
the unified 24-bit address space, and the address ranges of the different
spaces do not overlap. To promote code efficiency, the ZNEO CPU sup-
ports shorter 16-bit addressing for the memory located in the address
ranges 00_0000H-00_7FFFH and FF_8000H-FF_FFFFH. Figure 3 shows
the physical layout of memory spaces available in the ZNEO architecture.
