The MCF8316A supports an I²C serial communication interface that allows an external controller to send and receive data. This I²C interface lets the external controller configure the EEPROM and read detailed fault and motor state information. The I²C bus is a two-wire interface using the SCL and SDA pins (open-drain IOs) which are described as follows:

• The SCL pin is the clock signal input.
• The SDA pin is the data input and output.

SLEW_RATE_GPIO can be used to set the pull-down drive strength of the I²C pins. The 50-ns glitch filter in the receive signal path of the I²C pins is always enabled and cannot be bypassed.
