TDC7201: TDC7201 Trigger Signal problem in multi-cycle averaging

I'm using your TDC7201 chip for laser ranging. At the moment, I'm using measurement mode 1. When using a single measurement, the chip can work properly, the Clock_count register, calibration register 1, 2 can read the data, the completion of the interrupt signal is also normal. But there were some problems trying to multi-cycle averaging: I configured the AVG_CYCLES of TDCx_CONFIG1 's Trigg_edge,tdcx_config2, and then I placed TDCX_CONFIG1 Start_ The MEAS bit is measured and it is found that the method of multiple measurements does not work properly, and the MCU pin does not capture the trigger signal. My register configuration is: TDCx_CONFIG1 = {0X01},tdcx_config22 = {0x50}. Does this pattern use anything to be aware of, and can I use the pattern under mode 1?
