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

Notes:
1. These outputs function as open-drain outputs in Normal Parallel Port mode, and function as CMOS drivers when the EPP-
2. The parallel port interface BUSY input must have an external pullup if the parallel port is to be used in EPP mode. If this pullup
All inputs that have VCC clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
Notes:
1. These pins are terminated externally per bus option selection.
All inputs that have VCC clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
