• Processor mode control register (PMC)
3.1.3 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 general-purpose registers.

PMC register is described below.
This register selects the flash memory space for mirroring to area from F0000H to FFFFFH.
PMC can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets this register to 00H.
Cautions 1. Set PMC only once during the initial settings prior to operating the DMA controller. Rewriting
78K0R/Lx3 microcontrollers 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
Address: FFFFEH After reset: 00H R/W
2. After setting PMC, wait for at least one instruction and access the mirror area.
