PDSP16350 I/Q Splitter/NCO

DIN33:0 Data bus for the input register. This input register provides a 34 bit, incremental or absolute, phase value, if the mode pin is low. Alternatively if the mode pin is high, it provides either an 18 bit phase increment value, via D17:0, and a 16 bit scale value via D33:18 or a 34 bit phase .
