DESCRIPTION

The Tcl drivers upport code provides pre-defined Tcl variables in the CVMUSBReadoutList top level namespace. These variables contain the values of VME address mofifiers. Using them both make Tcl driver code more readable and mean that the programmer does not need to know the values of the VME bua address modifiers.

The meaning of these variables should be evident from their names. We will, therefore, not describe them further in this document. Note, however that if you are performing a block transfer, you must use the appropriate block transfer address modifier to force the controller to use BLT transfer cycles.
