3.2 Operation Modes
The microcomputer is placed in one of the following modes depending on how CPU operation mode is set by
MOD0 and MOD1 pins. The operation mode used for rewriting the internal flash memory is described separately
in Section 6.5, “Programming the Internal Flash Memory.”
Table 3.2.1 Operation Mode Settings
MOD0 MOD1 Operation mode (Note 2)
VSS VSS Single-chip mode
VSS VCCE External extension mode
VCCE VSS Processor mode (FP = VSS)
VCCE VCCE Reserved (use inhibited)
Note 1: Connect VCCE and VSS to the VCCE input power supply and ground, respectively.
Note 2: For the operation mode used to rewrite the internal flash memory (FP = VCCE) which is not shown in the above
table, see Section 6.5, “Programming the Internal Flash Memory.”
The internal ROM and extended external areas are located differently depending on how operation mode is set.
(All other areas in the address space are located the same way.) The diagram below shows how the internal ROM
and extended external areas are mapped into the address space in each operation mode. (For flash rewrite mode,
see Section 6.5, “Programming the Internal Flash Memory.”)
