Does STM32WB55 have embedded pull-up resistor on USB_DP?

PLilj.1 · ‎2021-10-29

In AN4879 FAQ it is stated to check "Table 3. USB implementation in STM32 devices" whether the USB_DP line has an embedded pull-up resistor.

STM32WB55 is not in that list. Can you confirm if the STM32WB55 has embedded pull-up resistor on USB_DP or not?
