Fc9-type-16-icon.png Channel
Channel selection 
Fc9-type-5-icon.png SDA
Pin used for SDA (data signal) 
Fc9-type-5-icon.png SCL
Pin used for SCL (clock signal) 
Fc9-type-16-icon.png Baud Select
Baud rate option selector 
Fc9-type-14-icon.png Baud Rate
Baud rate to be used 
Fc9-type-7-icon.png Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.  
Fc9-type-7-icon.png Use LDAC Pin
Allows the LDAC pin to be driven from an output pin on the microcontroller. If not used then tie the LDAC pin to GND to allow the DAC to function.
