Note 1: VCC and VSS are connected to +5 V and GND, respectively.
Note 2: For internal flash memory rewrite mode (when FP=VCC) not listed in the above table, refer to
Section 6.5, "Programming the Internal Flash Memory."
The locations of the internal ROM and external extended areas in the address space of the 32172/
32173 vary depending on its operation mode. (All other areas in address space located the same
way.) Also, during external extended mode, the available size of the external extended area varies
