GenDig - Config

Data from the Configuration zone can be included in the GenDig calculation. Data are always included in 32-byte blocks and only one block may be included on any given GenDig calculation. The Nonce command must be run prior to the first GenDig command to load a value into TempKey. Subsequent GenDig commands will use the value stored in TempKey from the previous GenDig operation.
