Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0033] see Figure 1-Figure 6 , first, construct the first latch LATCH1 and the second latch LACHT2. Among them, the first latch LATCH1 reads data when the input clock is low, and latches data when it is high; the second latch LATCH2 reads data when the input clock is high, and latches data when it is low , and both the CLR and RST terminals of the first latch LATCH1 and the second latch LACHT2 are active low. When both the CLR and RST terminals are high level, the first latch LATCH1 and the second latch LACHT2 enter the normal working state, and when CLK is low, the first latch LATCH1 reads the signals of the D and DB terminals (D, DB are mutually inverting signals) and output at Q1 and Q1B terminals, while the output terminal of the second latch LACHT2 remains in the original state; when CLK becomes high level, the output terminal of the fi...
