How should we handle sync/reset pin during power up? We will be using an external reference clock and will be programming the output voltage with either vset or the PMBUS. Set point is .85V so the scale loop is set to 1.

Hi Michael
You can use the FORCE_SYNC bit in the MISC_CONFIG_OPTIONS (MFR_SPECIFIC_32) (F0h) to use the SYNC function when using VSET.
