Data Propagation

The VTSRead that you create as a subroutine of your driver is responsible for delivering the data that it read from the I/O device. This is best done by using the RefreshData module within the scope of the CallBackObj parameter of the VTSRead module. If your driver needs to invalidate all data due to a communication failure, use the NoData module within the scope of the CallBackObj parameter of the VTSRead module.

RefreshData is provided for you as part of the VTSDriver module.
