STM32WB55xx

Functional overview

9. Some peripherals with wakeup from Stop capability can request HSI16 to be enabled. In this case, HSI16 is woken up by

the peripheral, and only feeds the peripheral which requested it. HSI16 is automatically put off when the peripheral does not

need it anymore.

10. The HSE can be used by the RF subsystem according with the need to perform RF operation (Tx or Rx).

11. MSI maximum frequency.

12. In case RF will be used and HSE will fail.

13. UART and LPUART reception is functional in Stop mode, and generates a wakeup interrupt on Start, address match or

received frame event.

14. I2C address detection is functional in Stop mode, and generates a wakeup interrupt in case of address match.

15. I/Os can be configured with internal pull-up, pull-down or floating in Standby mode.

16. I/Os can be configured with internal pull-up, pull-down or floating in Shutdown mode but the configuration is lost when

exiting the Shutdown mode.
