I had posted this query earlier as well but to no use. I am trying to generate 4 signals at digital pins of ADP3450 using waveforms. Each signal has a frequency of 1khz/100hz with each signal having 1000 samples each. The fourth signal is much more straightforward and is on for the initial half-cycle and then off.  In the first attempt, the "patterns" is used in BUS Mode with D0-D3 configured for generating these waveforms with a "Parameter1" frequency set using the formula frequency*number
