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 33 are derived from tests performed under ambient

temperature and supply voltage conditions summarized in Table 18: General operating

conditions. The provided curves are characterization results, not tested in production.
