1) PLL Jitter not included. Should be considered additionally, corresponding to the used baudrate. The duty cycle can be
adjusted using the BITCON.SAMPLEPOINT bitfield with the finest granularity of T_MAX = 1 / f_MAX.
2) Positive deviation lenghtens the high time and shortens the low time of a clock period. Negative deviation does the
opposite.
