For OEM-specific WPCE773LA0DG:

• Ensure the LPC Clock and Reset timing requirements are met.
• Verify GPIO assignment matches your BIOS expectations.
• Ensure Decoupling Capacitors are placed near the power pins (VCC) to prevent noise.

Locate the LPC Interface pins (LAD0-LAD3, LFRAME#, LCLK) to see how it communicates with the Chipset/PCH. 2. The Block Diagram
