Figure 3-2 External Code Memory, EA = 1.
3.10.2
This mode implements the internal eight-kbyte block of RAM (starting at 0) as combined code and data memory. When external
RAM or ROM is added, the external read and write strobes are suppressed for memory spaces that exist inside the chip. This
allows the user to connect a 64-kbyte memory without requiring address decodes to keep clear of internal memory spaces.
Only the internal eight kbytes and scratch pad 0.5 kbytes RAM spaces have the following access:
