| 9 | PD4(MODE) | Input | Working mode switching pin, when the pull-down time is greater than 500ms, the working mode is switched. |
| 10 | PA1(BAUD_R) | Input | The UART_BAUD_RESET pin is used to reset the baud rate of the device. It defaults to a high level when powered on. In any mode, if the pin is pulled down for more than 1000ms, the serial port parameters of the module will restore the default 11520 |
| 11 | PB1(ACK) | Output | The ACK pin is used to indicate the status of the last user datatransmission. The pin is pulled low before the transmission is started, and the pin is pulled high after the transmission is successful |
