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 6.6, “Programming the Internal Flash Memory.”

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 6.6, “Programming the Internal Flash Memory.”

The internal ROM and external extension areas are located differently depending on how operation mode is set.

(All other areas in the address space are located the same way.) The following diagram shows how the internal

ROM and external extension areas are mapped into the address space in each operation mode. (For flash

rewrite mode, see Section 6.6, “Programming the Internal Flash Memory.”)
