TPS659037 PMIC automatic power-on

I understand that for the TPS659037 PMIC to apply power to the AM5728 when the PMIC is itself powered (without the use of a power-on switch) the POWERHOLD input of the PMIC must be tied to the always-on supply LDOVRTC_OUT.  

In this instance, assuming a boot configuration of BOOT1=1, how should PWRON be tied?  Pulled-up to 3.3V?

Thanks
