| GPP_B08/BK4/SBK4/ISH_GP4/USB-C_GPP_B08 | OD | Blink BK 4: This function provides the blink (or PWM) capability. The blink/PWM frequency and duty cycle is programmable through the PWM Control register. Refer to Volume 2 for details. |
| GPP_A15/DNX_FORCE_RELOAD/USB-C_GPP_A15 | I | Download and Execute (DnX): Intel® CSME ROM samples this pin any time ROM begins execution. This includes the following conditions: - G3 Exit.
- Sx, Moff Exit.
- Cold Reset (Host Reset with Power Cycle) Exit.
- Warm Reset (Host Reset without Power Cycle) Exit if Intel® CSME was shutdown in Warm Reset.
- 0 => No DnX; 1 => Enter DnX Mode.
This pin must not be sampled high at the sampling time for normal operation. |

| SKTOCC# | N/A | Socket Occupied: Pulled down directly in the processor package to the ground. System board designers may use this signal to determine if the processor is present for safety purposes, it helps to avoid accidentally applying power to the socket while nothing is installed into the socket. If the customers do not want to use or do not need to use the pin(PKG without socket), they can leave it floating. |
