1. Legend: Y = yes (enabled). O = optional (disabled by default, can be enabled by software).R = retained, - = not available.
Gray cells highlight the wake-up capability in each mode.
2. The flash memory can be configured in power-down mode. By default, it is not in power-down mode.
3. The SRAMs can be powered on or off independently.
4. Parity error interrupt or NMI wake-up from Stop mode.
5. Some peripherals with autonomous mode and wake-up from Stop capability can request HSI16 to be enabled. In this case,
the oscillator is woken up by the peripheral, and is automatically put off when no peripheral needs it.
6. The 2.4 GHz RADIO peripheral in autonomous mode request HSE32 to be enabled. In this case, the oscillator is kept
active by the peripheral, and is automatically put off when it no longer needs it.
7. I/O levels can be retained with pull-up, pull-down, or floating.
8. There are 8 wake-up pins available.
