All the registers in the DSP blocks are positive-edge triggered and cleared on power
up. Each multiplier operand can feed an input register or a multiplier directly,
bypassing the input registers.
The following variable precision DSP block signals control the input registers within the
variable precision DSP block:
•
CLK
•
ENA[2..0]
•
CLR[0]
