Embodiment Construction
[0022] The present invention will be further described below through specific embodiments.
[0023] The power input terminal VCC of the memory card can be turned on and off under the control of the processor. Generally, the power level of the memory card is high, and the power level of the memory card is low.
[0024] The memory card detection pin T1 is the detection pin of the memory card socket, generally the memory card exists as a low level, and the memory card does not exist as a high level.
[0025] The output detection pin T2 is connected to the processor detection pin of the system. The main processor judges whether there is a signal in the memory card through this pin, and then the system performs business processing such as memory card mounting.
[0026] refer to figure 1 , a memory card detection circuit, connected between the memory card power input terminal VCC and the memory card detection pin T1, including
[0027] A first switch circuit, the input terminal of...
