Each time one of the TOP_CTRL.TSENSE*_RESULT.DTEMP bit fields is updated with new temperature value, this value is also automatically stored into a 4-level deep FIFO and a timestamp is registered too. There are four FIFOs used to store a brief history for the last few temperature measurements and are also dedicated to temperature timestamping feature. Each FIFO has two fields.
The first one is 8 bits wide, 4 levels deep, and is intended to store the temperature values for the last four measurements. The second field is 24 bits wide, 4 levels deep, and acts like a counter for the number of temperature measurements. Each FIFO is composed of the following registers (supported for TSENSE0 and TSENSE1):
