NOTES :
1. When an I/O pin is set to "input", take care not to let the pin to have a floating address.
2. Keep test pins TEST1Z to TEST7Z normally open.
3. I/O pins MEMCKE

, FLCE1Z, FLRP1Z, EXCS1Z and MEMCLK are set to "output" when reset (RESETZ input is
Low level), while other I/O pins are "input".
