1. Legend: Y = Yes (Enable). O = Optional (Disable by default. Can be enabled by software). - = Not available , wakeup
highlighted in gray.
2. The Flash can be configured in power-down mode. By default, it is not in power-down mode.
3. The SRAM clock can be gated on or off.
4. SRAM2 content is preserved when the bit RRS is set in PWR_CR3 register.
