What is the maximum amount of time required after reset for a Pattern 11 on STM32U073

Moved from this thread.

What is the maximum amount of time required after bringing nRST high for a Pattern 11 MCU to determine that flash is blank, recognize that BOOT0 is high, and enter the ROM bootloader?  I suspect we may have a timing issue, in that my application may not be waiting long enough before interrogating the bootloader.  (I would test this right now, but we handed off the project to our customer some time ago... they will be testing it later today).  Is this maximum time specified anywhere in ST's documentation?
