3.9.1 Automatic Temperature Monitoring

The system monitor checks that the board and FPGA are being operated within the specified limits. If the
temperature is close to the limit, a "Warning Alarm" interrupt is set.
If a limit is exceeded, a "Critical Alarm" interrupt is set. After the Critical Alarm is set, there is a 5 second delay
before the system monitor unconfigures the FPGA by asserting its "PROG" pin.
The purpose of this mechanism is to protect the card from damage due to over-temperature. It is possible that it
will cause the user application and, possibly, the host computer to "hang".
The temperature limits are shown in Table Temperature Limits. Note that the Min and Max values include a 5°C
margin to prevent measurement errors triggering a false alarm.
