1. Guaranteed by characterization results.

2. This is a deviation for an individual part once the initial frequency has been measured.

3. Sampling mode means Low-power run/Low-power sleep modes with Temperature sensor disable.

4. Average period of MSI at 48 MHz is compared to a real 48 MHz clock over 28 cycles. It includes frequency tolerance + jitter

of MSI at 48 MHz clock.

5. Only accumulated jitter of MSI at 48 MHz is extracted over 28 cycles.

For next transition: min. and max. jitter of 2 consecutive frame of 28 cycles of the MSI at 48 MHz, for 1000 captures over 

28 cycles.

For paired transitions: min. and max. jitter of 2 consecutive frame of 56 cycles of the MSI at 48 MHz, for 1000 captures over

56 cycles.

6. Guaranteed by design.
