used, and thus the contents of the data flash can be read with the shorter code. However, the data flash area is not
mirrored to the SFR, extended SFR, RAM, and use prohibited areas.
The 78K0R/Ix3 mirrors the data flash area of 00000H to 0FFFFH, to F0000H to FFFFFH (set by the processor
By reading data from F0000H to FFFFFH, an instruction that does not have the ES registers as an operand can be
See 3.1 Memory Space for the mirror area of each product.
The mirror area can only be read and no instruction can be fetched from this area.
The following show examples.

For example, 02345H is mirrored to
F2345H. Data can therefore be read by
MOV A, !2345H, instead of MOV ES,
#00H and MOV A, ES:!2345H.
