In the “I2C Configuration” dialog window (Figure 2.2, ““I2C Configuration” dialog window”) you can change the settings of the I2C bus. To open this dialog window select "Options/I2C Configuration".
In the "I2C bus" drop list you can choose the frequency of the I2C bus. It can have one of the following values:
Fast mode (400 kHz);
Standard mode (100 kHz);
Any value in the range 2 kHz – 83 kHz.
Select the “Clock Synchronization” check-box to turn on the clock synchronization (Clock Stretching). This option is only available for the frequencies below or equal to "Standard-mode" (<=100 kHz). In "Fast-mode" this option is unavailable.
The “Clock Synchronization Timeout” field allows to change the clock stretching timeout value (integer number from 1 to 65535). Clock synchronization (clock stretching) timeout value specified as multiple of 100 microseconds.
