16.11 I²C Pad Control

For this family of devices, the I²C specific pads are available on RB4 and RB6 (20-pin devices only),and RC0 and RC1 pins. The I²C characteristics of each of these pins is controlled by the RxyI2C registers. These characteristics include enabling I²C specific slew rate (over standard GPIO slew rate), selecting internal pull-ups for I²C pins, and selecting appropriate input threshold as per SMBus specifications.
