Flash in power-down mode(5)
1. Data guaranteed by design, not tested in production.
2. tWU(WFI) = 2 x 1/fmaster + 7 x 1/fCPU
3. Measured from interrupt event to interrupt vector fetch.
4. Configured by the REGAH bit in the CLK_ICKR register.
5. Configured by the AHALT bit in the FLASH_CR1 register.
6. Plus 1 LSI clock depending on synchronization.
