按键及数码管显示驱动芯片，调试通过，有中文备注。CH452的真正2线接口，含低电平脉冲按键中断在内，只需要2个I/O引脚，兼容I2C/IIC时序
两线制方式SCL/SDA，按键中断由SDA产生，接单片机的脉冲/边沿中断引脚
对于频率低于24MHz的MCS51，为了节约传输时间，可以适当减少SCL/SDA之间的延时-Buttons and digital display driver chip debugging through, Chinese Remarks. Including CH452 true 2-wire interface with low pulse button interrupt, only two I/O pin compatible I2C/IIC timing two-wire, SCL/SDA, key interrupt generated by the SDA, connected to the microcontroller' s pulse/edge interrupt pin for frequencies below 24MHz of the MCS51, in order to save transmission time can be appropriate to reduce the delay between the SCL/SDA
