The EPROM is in a totally different bus, but you can put

Whether it is EPROM, ROM or RAM is irrelevant. In a Harvard Architecture
code and data are separate address address spaces.
The wiki says:
Harvard architectures are also frequently used in:
The wiki correctly refers to separate pathways for code and data, you

I CAN read. EPROM is normally used for code, and RAM for
data. But that distinction is blurred if you store
constant data in EPROM, for instance (as I said)
constant character strings or tables, whatever.
This is also used in other processors when character
strings are stored with the code...
