FILTER HDL CODER MATLA

Hi,
I want create a lowpass FIR FILTER with the followin spec.:
Fs=400MHz Fpass=55MHz Fstop=150MHz Apass=1 Astop=150
I have quantize the filter with 14bit in/out.
I have a doubt regarding "Filter Internals" when select the
"Rounding Mode" and "Overflow Mode". Is there a best setup for this parameter?

Thanks at all

BEst Regards
