9.2.2.2 Sizing Pullup Resistors

To get an estimate for the range of values that can be used for the pullup resistor, please refer to the application note SLVA689.Figure 9-3 and Figure 9-4 respectively show the maximum and minimum pullup resistance allowable by the I2C specification for standard-mode (100 kHz) and fast-mode (400 kHz) operation.
