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. | |

|
Console Data |
| Selects if the console data is automatically generated or not | |
|
|
API |
| Specifies the injector component on the panel to interact with to provide comms simulation. | |
