I am programming an LMX2595 in partial Assist mode, and will use the MUXOUT pin to confirm that the VCO is locked.I use frequency from 7.988GHz to 12GHz, each step is 2MHz with 2007 steps. But I found that MUXOUT is pulled up twice at 8002 MHz, while the frequency is stable and correct. Is there anything wrong?
And below are the initial registers(12000MHz), which are exported directly from the TICS pro software.

Whenever I change the frequency, I only write 13 registers,below are the 13 registers of 8002MHz. Those 13 registers are after the initial 112 registers.

The MUXOUT pin in the 2008 frequencies was finally pulled up a total of 2028~2030 times. Please tell me if there is something wrong.Thanks!
