1. RP = External pull-up resistance, fSCL = I2C speed,  
2. For speeds around 200 kHz, the tolerance on the achieved speed is of 5%. For other speed ranges, the  
tolerance on the achieved speed 2%. These variations depend on the accuracy of the external  
components used to design the application.
