Note 1: BRG is the value of the I²C Baud Rate Generator. Refer to Section 19. “Inter-Integrated Circuit (I²C™)”
(DS70330) in the “dsPIC33E/PIC24E Family Reference Manual”. Please see the Microchip web site for
the latest family reference manual sections.
2: Maximum pin capacitance = 10 pF for all I2Cx pins (for 1 MHz mode only).
3: Typical value for this parameter is 130 ns.
4: These parameters are characterized, but not tested in manufacturing.
