Why are there incorrect outputs after I reset the single multiply accumulate (MACC) engine half-band filter when the data is stored in Block Memory?
This issue is resolved in the FIR Compiler v.3.1.
This issue is due to a bug in how the data address is generated. To work around this issue, do not use the SCLR pin.
