The output voltage rises, the cathode voltage of TL431 drops, the P tube is turned on, and the output voltage drops.
But doesn't the transistor go directly to the ground when it is turned on? Is there

Sometimes you need to embed some assembly code in a C51 program. In this case, you can use the usual approach: write an assembly function according to the interface between C51 and assembly, and then
