The chosen pullup resistor must meet the I2C standard timings. In most circumstances, 2.2kΩ of total bus resistance to VDDIO is sufficient. The value of the pullup resistance used on both the SCL and SDA pins be matched is also recommended. For evaluating pullup resistor values for a particular design, see the I2C Bus Pullup Resistor Calculation Application Report.
