NM10 Express Chipset's System Management Bus controller.
SMB_ALERT#: SM Bus Alert line for System Management. Bidirectional signal, electrical level +3.3V_A with a 10kΩ pull-up resistor. It is managed by Intel
Express Chipset's System Management Bus controller. Any device place on the SM Bus can drive this signal low to signal an event on the bus itself.
GP0_I2C_CLK: general purpose I2C Bus clock line. Bidirectional signal, electrical level +3.3V_S with a 2k2Ω pull-up resistor. This I2C signal is derived from Intel
NM10 Express Chipset's General Purpose I/O pin GPIO6.
GP0_I2C_DAT: general purpose I2C Bus data line. Bidirectional signal, electrical level +3.3V_S with a 2k2Ω pull-up resistor. This I2C signal is derived from Intel
NM10 Express Chipset's General Purpose I/O pin GPIO7.
WDTRIG#: Watchdog Trigger Input. It is an active low signal, +3.3V_S voltage. This signal can be used to reset and restart, via Hardware, the embedded
microcontroller's internal Watchdog Timer (which is usually managed via Software using QuadMo747-x2000 dedicated API - Application Program Interface -
libraries).
WDOUT: Watchdog event indicator Output. It is an active high signal, +3.3V_S voltage. When this signal goes high (active), it reports out to the devices on the
Carrier board that the embedded microcontroller's internal Watchdog's timer expired without being triggered, neither via HW nor via SW.
THRM#: Thermal Alarm Input. Active Low +3.3V_P voltage signal with 10kΩ pull-up resistor, directly managed by Intel
the possibility, to carrier board's hardware, to indicate to the main module an overheating situation, so that the CPU can begin thermal throttling.
THRMTRIP#: Thermal trip output. Active Low +3.3V_S voltage signal with 4k7Ω pull-up resistor, directly managed by the Intel
This signal is used to communicate to the carrier board's devices that, due to excessive overheating, the CPU began the shutdown in order to prevent physical
damages.
BIOS_DISABLE#:onboard BIOS Disable input, active Low +3.3V_A voltage signal with 10kΩ pull-up resistor. When this signal is pulled down on the carrier board,
then module's SPI Flash will be disabled, and the module will boot using the BIOS code contained in an external Firmware Hub placed on LPC bus.
FAN_TACHOIN: External FAN Tachometer Input. +3.3V_S voltage signal, managed by ST Microelectronics STM32F100R4H6 microcontroller.
FAN_PWM_OUT: PWM output for FAN speed management, +3.3V_S voltage signal. It is managed by ST Microelectronics STM32F100R4H6 microcontroller.
SPKR: Speaker output, +3.3V_S voltage buffered signal, directly managed by Intel
3.2.3.15 Manufacturing signals
®
According to Qseven Standard specifications, rel. 2.0, on pin designed as MFG_NCx (pins 204, 207÷210) are carried the JTAG signal necessary to program
QuadMo747-x2000 embedded microcontroller.
The JTAG interface available on MFG_NCx pins is reserved only for the manufacturing phase; it must not be used by the customer.
It is not possible at all to use these pins to trace the software (for debug purposes).
