AM186ED AMD [Advanced Micro Devices], AM186ED Datasheet - Page 29

• Manufacturer Part Number: AM186ED
• Description: High Performance, 80C186- and 80C188-Compatible, 16-Bit Embedded Microcontrollers
• Manufacturer: AMD [Advanced Micro Devices]

Notes:
The following notes apply to both tables.
1. These pins are used by many emulators. (Emulators also use S2–S0, RES, NMI, CLKOUTA, BHE, ALE, AD15–
2. These pins revert to normal operation if BHE / ADEN is held Low during power-on reset.
3. When used as a PIO, input with pullup option available.
4. When used as a PIO, input with pulldown option available.
