COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
The following table gives the values to be written in
the I2CCCR register to obtain the required I
SCL line frequency.
Table 29. SCL Frequency Table
Legend:
R
f
NA = Not achievable
Note:
– For speeds around 200 kHz, achieved speed can have ±5% tolerance
– For other speed ranges, achieved speed can have ±2% tolerance
The above variations depend on the accuracy of the external components used.
