FIR compiler II parameter settings for sample rates below 1Mhz

Right. The documentation and user interface are not clear on this. I have also noticed that under some circumstances the frequency response plot is not computed correctly even though the impulse response is showing the correct values for the taps values entered. The documentation also doesn't make it clear that the frequency plot nyquist value is determined by the output sample rate in the case of multi rate filters. I guess I should have realized this when inspecting the plots, but since the frequency response plot was bad, I didn't know what was going on.
