• Manufacturer Part Number: ELANSC310
• Description: Single-Chip, 32-Bit, PC/AT Microcontroller
• Manufacturer: AMD [Advanced Micro Devices]

Notes:
All Pull-Up and Pull-Down resistor requirements are specified in ohms.
1. This pin is an “alternate pin function select input” that is sampled at reset. This pin functions as a normal serial port output
2. When this pin’s function is a DMA request input, it should be terminated with a pulldown resistor if not connected to an external
3. If this ÉlanSC310 microcontroller input is always driven to a known state, then no external termination is required.
4. If the pin is configured as an input, it should be terminated with a discrete pull-up or pull-down resistor, or it should always be
