1. Data guaranteed by design, not tested in production.

2. Measured from interrupt event to interrupt vector fetch.

3. tWU(WFI) = 2 x 1/fMASTER+ 67 x 1/fCPU.

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.
