AGND NC SENSE1_RETUR SENSE2_RETUR 13. Front panel audio header This header is for a chassis-mounted front panel audio I/O module that supports HD audio standard. Connect one end of the front panel audio I/O module cable to this header. • We recommend that you connect a high-definition front panel audio module to this header to avail of the motherboard's high- AAFP definition audio capability. PORT1 L PORT1 R PORT2 R SENSE_SEND PORT2 L • If you want to connect a high-definition front panel audio module to this header, set the Front Panel Type item in the BIOS setup to [HD Audio]. By default, this header is set to [HD Audio]. HD-audio-compliant pin definition 14. LPC Debug header This header allows connection to a LPC Debug card. • Scan the QR code to view the meaning of each debugging code. • Debugging codes are only available for ASUS LPC Debug cards. • Contact your region sales representative for LPC Debug cards ordering. +3V +3V CK_24M_LPC GND LPC_DEBUG PIN 1 S_LAD0 S_LAD1 S_LAD2 S_LAD3 S_LFRAME# O_LPT_XAFD#_R O_LPT_ERROR#_R O_LPT_XINIT#_R O_LPT_XSLIN#_R GND GND GND GND GND GND GND GND 15. LPT header The LPT (Line Printing Terminal) header supports devices such as a printer. LPT standardizes as IEEE 1284, which is the parallel port interface on IBM PC-compatible computers.

Speaker header The 4-pin header is for the chassis-mounted system warning speaker. The speaker allows you to hear system beeps and warnings. +5V GND GND Speaker Out SPEAKER PIN 1 17. SPI TPM header F_SPI_HOLD#_R T_SPI_MISO F_SPI_CS0#_R +3V_SPI NC S_PLTRST# VCCSPI This header supports a Trusted Platform Module (TPM) system with a Serial Peripheral Interface (SPI), allowing you to securely store keys, digital certificates, passwords, and data. A TPM system also helps enhance SPI_TPM PIN 1 network security, protects digital identities, and ensures platform integrity. T_SPI_MOSI T_SPI_CLK GND F_BIOS_WP#_R S_SPI_TPM_CS2# S_SPI_TPM_IRQ# 18. 10-1 pin System Panel header This header supports several chassis-mounted functions. • System power LED (2-pin +PWR_LED-) This 2-pin header is for the system power LED. Connect the chassis power LED cable to this header. The system power LED lights up when you turn on the system power, and blinks when the system is in sleep mode. 1-4 Chapter 1: Product Introduction
