PLL_HILO event status

Hi, team.

We found a problem when using DWM3000. We configured RF as channel9 and enable receiver. Then we found PLL_HILO event status in SYS_STATUS. The PLL HILO means clock pll losing lock. But it doesn’t seem to affect communication.


And we didn’t see this when we configured RF as channel 5.


And there’s another question. The user manual said that the SYS_PANIC in FINT_STAT will be set if PLL_HILO set in SYS_STATUS. But the printout did not.


Is the above problem normal? Is it the error of DW3000?
