Hi team,

Is a 32.768k crystal necessary in PDN0B?

I mean, the crystal for TPS6594, thanks!

In a multi-PMIC PDN, the 32kHz crystal is not needed on PMIC-B since PMIC-A has a 32kHz crystal.

yes, PMICB doesn't connect a crystal, I mean for PMICA(TPS65941212). there is a crystal but we didn't get any output wave form at Pin 38 and 39.
