Notes:
1.
FMAX = BRGCLK/(min_divider*prescale. Where prescaler=25-I2MODE[PDIV]; and min_divider=12 if digital filter disabled
and 18 if enabled.
Example #1: if I2MODE[PDIV]=11 (prescaler=4) and I2MODE[FLT]=0 (digital filter disabled) then FMAX=BRGCLK/48
Example #2: if I2MODE[PDIV]=00 (prescaler=32) and I2MODE[FLT]=1 (digital filter enabled) then FMAX=BRGCLK/576
