An external resistor is not required between OSC32_IN and OSC32_OUT and it is forbidden
to add one.
Internal clock source characteristics
The parameters given in Table 42 are derived from tests performed under ambient
temperature and supply voltage conditions summarized in Table 22.
The provided curves are characterization results, not tested in production.
