The XEM7360 supports the FrontPanel Device Settings in the table below, accessible from the FrontPanel Application as well as the Device Settings API.
Fan Control Device Settings
You may optionally connect a fan to JP1 (Molex 53398-0271). This connector drives a 3.3v PWM signal to the fan according to the Device Settings. For most applications, we recommend binary operating mode and enabling the fan at all times. You may optionally configure a proportional control whereby the PWM output is proportional to the measured temperature of the FPGA die.
Vadj1 output voltage specified in 10’s of mV. For example, “330” would set Vadj1 = 3.3v.
Vadj2 output voltage specified in 10’s of mV. For example, “330” would set Vadj2 = 3.3v.
Vadj3 output voltage specified in 10’s of mV. For example, “180” would set Vadj3 = 1.8v. Vadj3 connects to a High Performance bank and supports a maximum of 1.8v.
(1:0) : Vadj1 mode
0=Minimum setting (0.8V)
DEFAULT: 170 (0xAA) - Each Vadj at mode 2 with output enabled.
Read-only register that contains the FMC1 signal status during runtime.

[6:5] - GA[0:1]
In binary mode, 0=disable, 1=enable
In temperature slope mode, the number here represents the lower threshold (in degrees Celsius) for temperature-dependent operation.
At THRESH+16C, fan control PWM=50%.
At THRESH+32C, fan control PWM=100%.
