Table 27 Thermal Management Signal Descriptions; Table 28 Fan Control Signal Descriptions - Congatec Qseven conga-QMX6 User Manual

Caution
The MFG_NC4 pin is high active on the conga-QMX6 module. This means that the MFG interface on the edge connector functions by default
as JTAG interface. Therefore, do not use the MFG interface for UART purposes or externally pull the MFG_NC4 pin to ground. Failure to
adhere to this warning may result to back-driving which can damage the module.
If you need the UART function on the MFG interface, then you require a customized conga-QMX6. For more information, contact
congatec support.
Table 27 Thermal Management Signal Descriptions
Signal Pin # Description
THRM# 69 Thermal Alarm active low signal generated by the external hardware to indicate an
over temperature situation. This signal can be used to initiate thermal throttling.
Thermal Trip indicates an overheating condition of the processor. If 'THRMTRIP#'
THRMTRIP# 71
goes active the system immediately transitions to the S5 State (Soft Off).
Table 28 Fan Control Signal Descriptions
Signal Pin # Description
FAN_PWMOUT 196 Primary functionality is fan speed control. Uses the Pulse Width Modulation (PWM)
/GP_PWM_OUT1 technique to control the Fan's RPM based on the CPU's die temperature. When not in use
for this primary purpose it can be used as General Purpose PWM Output.
FAN_TACHOIN 195 Primary functionality is fan tachometer input. When not in use for this primary purpose it can
/GP_TIMER_IN be used as General Purpose Timer Input.
