+3.3 V I/O pin (12 mA, 98 k$ pull-up
MEMD0 to MEMD31
resistor installed)
+3.3 V I/O pin (8 mA, 98 k$ pull-up TEST1Z to TEST7Z, EXDACK0Z to EXDACK1Z, EXINTZ, CFRDBY,
resistor installed) or input pin
CFWAITZ, CFD0 to CFD15, ASDI, SCLK0, ICEFIQZ
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 MEMCKE2, MEMCKE3, FLCE1Z, FLRP1Z, EXCS1Z and MEMCLK are set to "output" when reset (RESETZ input is
Low level), while other I/O pins are "input".
