Notes to
(1) Block output for accumulator overflow and saturate overflow.
(2) Block output for saturation overflow of chainout.
(3) When the chainout adder is not in use, the second adder register banks are known as output register banks.
(4) You must connect the chainin port to the chainout port of the previous DSP blocks; it must not be connected to general routings.
