DATA MEMORY ADDRESSING
The
μ
PD78362A is provided with many addressing modes that improve the operability of the memory and
can be used with high-level languages. Especially, an area of addresses FC00H-FFFFH (F700H-FFFFH
in the
μ
PD78361A) to which the data memory is mapped can be addressed in a mode peculiar to the functions
provided in this area, including special function registers (SFR) and general-purpose registers.

μ
PD78361A)
Caution
For word access (including stack oprations) to the main RAM area (FE00H-FEFFH), the
address that specifies the operand must be an even value.
