5.6 Memory Map
The CY8C38 8051 memory map is very similar to the MCS-51
memory map.
5.6.1 Code Space
The CY8C38 8051 code space is 64 KB. Only main flash exists
in this space. See the
5.6.2 Internal Data Space
The CY8C38 8051 internal data space is 384 bytes, compressed
within a 256-byte space. This space consists of 256 bytes of
RAM (in addition to the SRAM mentioned in
18) and a 128-byte space for special function registers (SFR).
See
registers R0-R7. The next 16 bytes are bit-addressable.
