The current potential of read-write motion or adjustment first signal is normal current potential, then is transferred to the terminal assembly, the set of terminal
Part carries out reading and writing data movement.
7. according to claim 6 prevent integrated circuit from malfunctioning method, which is characterized in that the bus is built-in integrated
Circuit bus, the first line are clock lines, and second route is data circuit.
8. according to claim 6 prevent integrated circuit from malfunctioning method, which is characterized in that first signal is clock
Signal, the second signal are data-signals；The current potential of the clock signal has the first current potential and the second current potential, wherein first
Current potential is higher than the second current potential；The abnormal potential is between first current potential and second current potential；The normal electricity
Position is first current potential.
9. according to claim 6 prevent integrated circuit from malfunctioning method, which is characterized in that the clock signal of the detecting
Current potential be first current potential when, the clock signal and the data-signal are transferred to the terminal assembly, the end
Component is held to carry out reading and writing data movement；When the current potential of the clock signal of the detecting is the abnormal potential, institute is sent a command to
Stating terminal assembly makes it terminate the reading and writing data movement or adjusts current potential first current potential of the clock signal, then
The clock signal and the data-signal are transmitted to the terminal assembly, the terminal assembly carries out reading and writing data movement.
10. according to claim 1 prevent integrated circuit from malfunctioning system, which is characterized in that the clock of the detecting is believed
Number current potential be first current potential when, the clock signal and the data-signal are transferred to the terminal assembly, it is described
Terminal assembly carries out reading and writing data movement；When the current potential of the clock signal of the detecting is the abnormal potential, send a command to
The terminal assembly makes it terminate the reading and writing data movement or adjusts current potential first current potential of the clock signal,
The clock signal and the data-signal are transmitted again to the terminal assembly, and the terminal assembly carries out reading and writing data movement.
