Note 4-8-1: The value of Tfilt is determined by the values of the register SLIC0PCNT, bits 5 and 4 (BRP1, BRP0) and
the system clock frequency.

Set bits (BPR1, BPR0) so that the value of Tfilt falls between the following range:
250ns ≥ Tfilt > 140ns
Note 4-8-2: Cb represents the total loads (in pF) connected to the bus pins. Cb ≤ 100pF
Note 4-8-3: When not specified, VDD3=1.6V to 3.6V (VDD3≤VDD)
