1. Data guaranteed by design.

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.
