3.2 Operation Modes
The 32170 is placed in one of the following modes by setting its operation mode (using MOD0 and
MOD1 pins). For details about the mode used to rewrite the internal flash memory, refer to Section
6.5, "Programming of Internal Flash Memory."

of Internal Flash Memory."
The internal ROM and extended external areas are located differently depending on the 32170's
operation mode. (All other areas in address space are located the same way.) The address maps of
internal ROM and extended external areas in each mode are shown below. (For flash rewrite mode
(FP = VCC) not listed in the above table, refer to Section 6.5, "Programming of Internal Flash
Memory.")
