2.11 – CPU Thermal-Trip (JP23)
The processor protects itself from overheating by the use of an internal integrated thermal sensor.
When the Thermal-Trip is enabled, the system will shut off if temperature reaches about 135º
Celsius at CPU junction temperature. The processor then stops all its executions.

is an external LED header to indicate CPU1
signal PROCHOT# status. When CPU1 gets
too hot, the CPU1 signal PROCHOT# will be
asserted before CPU1 reaches cataclysmal
failure or damage.
The onboard LED (D1) acts as same as J1 to
indicate CPU1 processor overheating.
