What datasheet? The datasheet for the 8051 compatible device I am
using (CY68013) does not make it clear if instruction RAM and data
RAM are separate or overlap in the first 128 bytes. At least not
that I can see.

The original 8051 datasheet won't help either, since the original 8051
didn't have iRAM. It had ROM.
