Section 6.12.2.1.1 lists the I2C timing requirements. Section 6.12.2.1.2 lists the I2C switching characteristics. Figure 6-67 shows the I2C timing diagram.
To meet all of the I2C protocol timing specifications, the I2C module clock must be configured in the range from 7 MHz to 12 MHz.
A pullup resistor must be chosen to meet the I2C standard timings. In most circumstances, 2.2 kΩ of total bus resistance to VDDIO is sufficient. For evaluating pullup resistor values for a particular design, see the I2C Bus Pullup Resistor Calculation Application Report.
