Using MAX1619 to measure FPGA temperature, the local and remote values of MAX1619 read by the cpld fluctuates significantly when the FPGA is running certain programs. This seems to be totally abnormal. What might be the cause of this?

If both local and remote temperatures are fluctuating, please check the power supply to see if there is any significant noise. For analog measurements, external interference will generally result in fluctuation of the measurement result.

MAX1619 reads remote temperature measurement once every 4 seconds. Can this frequency be configured to, for example, once every second or once every 2 seconds?

Yes. The default setting upon powering on is once every 4 seconds. It can be configured via register settings as shown in the table below:
