STM32U0 Bootloader Timings

I am looking at revision 64 of the the AN2606 application note.
https://www.st.com/resource/en/application_note/an2606-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdf

Section 89 of this document gives some tables for some timings for a number of different processors. I am using the STM32U073 processor but I cannot find entries in tables 200, 201 and 202 for this part.
