21.5. I2C Controller Programming Model

This section describes the programming model for the I2C controllers based on the two master and slave operation modes. †

Note: Each I2C controller should be set to operate only as an I2C master or as an I2C slave, never set both simultaneously. Ensure that bit 6 (IC_SLAVE_DISABLE) and 0 (IC_MASTER_MODE) of the IC_CON register are never set to 0 and 1, respectively. †
