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 chararacterization results, not tested in production.
