5.5.2. Thermal Status Register

You can use the fields of the Thermal Status register to monitor the thermal status of the HBM device and controller.

Because CATTRIP is a critical condition, it is advisable for your design to detect this condition by monitoring the CATTRIP output signal from the HBM IP, instead of by polling this register. To read the thermal status register, issue a read command to the register at offset 32’h0100.

Table 33.  Thermal Status Register
Bits Access Name Description
7:0 RO TEMPRD Temperature readout from the HBM device, expressed in degrees Celsius.
27:8 RO Reserved Reserved.
30:28 RO TEMP Raw HBM device temperature compensated refresh band value: reflects the TEMP[2:0] output of the HBM device. The HBM controller uses this to adjust the frequency of memory refreshes.
31 RO CATTRIP HBM device catastrophic trip indication: reflects the catastrophic trip indication reported by the HBM device on its CATTRIP output.
