3.3
Figure 3.3
Areas that can be accessed vary depending on processor mode and the status of each control bit. Figure
3.3 shows the Accessible Area in Each Mode.
In single-chip mode, the SFRs, internal RAM, and internal ROM can be accessed.
In memory expansion mode, the SFRs, internal RAM, internal ROM, and external areas can be accessed.
Address space is expandable to 4 MB with the memory area expansion function.
In microprocessor mode, the SFRs, internal RAM, and external areas can be accessed. Address space is
expandable to 4 MB with the memory area expansion function. Allocate ROM to the fixed vector table
from FFFDCh to FFFFFh.

Single-chip mode and memory expansion mode
Microprocessor mode
Accessible Area in Each Mode
- The PM10 bit in the PM1 register is 1
- The PRG2C0 bit in the PRG2C register is 0 (program ROM 2 enabled)
- The PM13 bit in the PM1 register is 1
- The PM10 bit is 0 (addresses 0E000h to 0FFFFh are used as the CS2 area)
- The PRG2C0 bit is 1 (program ROM 2 disabled)
(addresses 0E000h to 0FFFFh are used as data flash)
(all areas in internal RAM, and the program ROM 1 area from 80000h are usable)
