• Description: Single-Chip, 32-Bit, PC/AT Microcontroller
• Manufacturer: AMD [Advanced Micro Devices]

Notes:
1. These signals are active during reset.
2. These pins always default to their DRAM interface function.
3. The drive strength for these pins is programmable. E is the default.
All inputs that have VCC Clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
