| colspan="2" | 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. &nbsp;
