Fc9-type-21-icon.png Address
Address of the SM324 IC, Default address is 16. Valid Address range = 8 to 127

Pin used for SCL (clock signal) 
Fc9-type-16-icon.png SCL Remap Pin
 
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.
