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

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

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

@48 MHz clock.

4. Only accumulated jitter of MSI @48 MHz is extracted over 28 cycles.

For next transition: min. and max. jitter of 2 consecutive frame of 28 cycles of the MSI @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 @48 MHz, for 1000 captures over 56 cycles.

5. Specified by design, not tested in production.
