How could I soft-reset for HMC703LP4E in HMC mode?

Hello.

 

I am curious about the register setting of the HMC703LP4E.

The hardware/software configuration is as follows.

The FPGA is controlling the HMC703LP4E. The SPI mode is HMC mode.

The FPGA continues to monitoring the LDO voltage of the HMC703LP4E.  When the LDO voltage of the HMC703LP4E goes to 0V, the FPGA automatically resets the HMC703LP4E.

 

At any moment, HMC703LP4E becomes abnomal.

If the HMC703LP4E is abnormal when the initial power is applied, the HMC703LP4E remains abnormal even if the FPGA is reset.

So before FGPA does an automatic reset of HMC703LP4E, I want to perform a soft reset of HMC703LP4E first.

 

There is information on open mode on 6-45. I could not find soft-reset information for HMC MODE.

 

How could I soft-reset for HMC703LP4E in HMC mode?
