At this time, when the protocol selection unit transmits subsequent signals, the protocol selection unit transmits standard signals to the target external chip through the current transmission channel and the target pin channel. When the chips with other protocols need to be switched to communicate, the state bit of the pin is only needed to be reset, the steps of confirming the current protocol conversion rule, the current transmission channel and the target pin channel are sequentially executed, and then signal transmission is carried out, so that data interaction can be carried out on all external chips through a time-sharing communication method. Or after the chip is powered on again, protocol configuration information is determined again, then the steps of confirming the current protocol conversion rule, the current transmission channel and the target pin channel are sequentially executed, and then signal transmission is carried out.
