Both these waveforms are produced simultaneously, with 16 bit amplitude accuracy, and are synthesised using a 34 bit phase accumulator. The more significant bits of this provide 16 bits of phase accuracy for the sine and cosine look up tables. With a 20 MHz system clock, waveforms up to 10 MHz can be produced, with 0.001 Hz resolution.
