Digital systems use discrete values (i.e. 0 or 1) rather than continuous signals (i.e. 0.0 to 1.0 inclusive) in order to transmit information. So in that case, DNA having only 4 possible bases can be described as a digital code, but then so could practically anything that can be meaningfully translated into discrete values.
I don't think there is anything special about it; if you are trying to infer that because it is a digital code it must come from intelligence. Digital codes are an invention of man, yes, but they are merely a way of interpreting certain types of data.
