4.1.3 Internal data memory space
general-purpose register banks consisting of eight 8-bit registers per bank are assigned to the 32-byte area of FFEE0H to
FFEFFH of the internal RAM area. However, instructions cannot be executed by using the general-purpose registers.

The 78K0R/Kx3-L products incorporate the following RAMs.
The internal RAM can be used as a data area and a program area where instructions are written and executed. Four
The internal RAM is used as a stack memory.
Cautions 1. It is prohibited to use the general-purpose register (FFEE0H to FFEFFH) space for fetching
2. While using the self-programming function, the area FFE20H to FFEFFH cannot be used as stack
instructions or as a stack area.
memory. Furthermore, the areas of FF300H to FF6FFH and FDF00H to FE2FFH also cannot be
used with the
78F1029, and 78F1030, respectively.
