100 kHz mode — 300 ns CB is specified to be
from 10 to 400 pF
400 kHz mode 20 + 0.1 CB 300 ns
1 MHz mode 
(Note 2)
— 100 ns
Note 1: BRG is the value of the I
2
C™ Baud Rate Generator.
2: Maximum pin capacitance = 10 pF for all I2Cx pins (for 1 MHz mode only).
3: The typical value for this parameter is 104 ns.
