AM186ES Advanced Micro Devices, AM186ES Datasheet - Page 36

• Manufacturer Part Number: AM186ES
• Description: microcontrollers provide a low-cost/ high-performance solution for embedded system designers who wish to use the x86 architecture.
• Manufacturer: Advanced Micro Devices

Notes:
1. These pins are used by emulators. (Emulators also use
2. These pins revert to normal operation if BHE/ADEN
3. When used as a PIO, input with pullup option available.
4. When used as a PIO, input with pulldown option available.
