对于单片机与看门狗的连接，单片机的RST与看门狗的/RESET/RESET相连接，看门狗的SI连接P1.1，SCK 连接P3.4，SO连接P3.3，/CS连接P3.5。其中SO是串行输出口，单片机可以通过该口看门狗状态寄存器等的信息。其他管脚之间的连接以及该遵循的规定将会在下面参数设计部分详细说明，此不赘述。需要注意的是在往看门狗写数据的-Connection with the watchdog for the MCU, MCU RST and watchdog/RESET/RESET is connected to the SI watchdog connection P1.1, SCK connection P3.4, SO connection P3.3,/CS connection P3 .5. Where SO is the serial output port, the port through the MCU watchdog status register and other information. The connection between the pins and the other to follow the provisions of the parameters of design in the following section will detail, this does not go into details. Note that the data in writing to the watchdog
