Figure 4–4. Half-DSP Block Architecture
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.

All DSP block registers are triggered by the positive edge of the clock signal and are
cleared upon power up. Each multiplier operand can feed an input register or feed
directly to the multiplier, bypassing the input registers. The following DSP block
signals control the input registers in the DSP block:
