PIO Pin Assignments
Notes:
1. These pins are used by emulators. (Emulators also use S2–S0, RES, NMI, CLKOUTA, BHE,
2. These pins revert to normal operation if BHE/ADEN (186) or RFSH2/ADEN (188) is held Low
3. When used as a PIO, input with pullup option available.
4. When used as a PIO, input with pulldown option available.
