10.With typical firmware. The exact value depends on the firmware variant loaded and the firmware configuration.
Oscillator: pin XIN, XOUT
In production the actual oscillation of the oscillator and duty cycle will not be tested. The production test will be based on
the static parameters and the inversion from XIN to XOUT in order to guarantee the functionality of the oscillator.

11. This parameter is not tested in production.
12.These parameters will not be measured in production as the performance is determined by a digital circuit. Correct operation of this circuit
will be guaranteed by the digital test patterns.
