Thermal shutdown on ADuC845

Hi,

 

I was looking into ADuC 845 manual but I do not found anything about it.

In my application because of system inertia, temperature can reach 128 to 129 degC for short period of time.

I am using ADuC 845 internal temp sensor, whenever reading is 127 degC (maximum for this sensor), ADuC itself is going into same how "partial hold", (DAC is working, PWM also, but ADC and external interrupt not)as soon as reading is 126 everything is back to order. This "freezing" happend regardles I am reading data from  internal temp sensor or not.

 

Can I do something  to disable this "Thermal shutdown" option?

 

Regards

Slawek
