5.2.13 Shut Down Device (OFF)

Format: OFF

Use this command to enter the Shutdown state. The system stays in Extreme Deep Sleep (XDS) mode in this state, and it consumes extreme low power. A hard reset or pulling the UART_RX_IND (UART RX Indication, PB9) pin low can bring the system back to Active mode. The following figure illustrates the wake-up timing of the RNBD451 module using the UART_RX_IND (UART RX Indication, PB9) pin.

Note: T1: The time prior to UART data. This time must be greater than 25 ms.
Note: This command causes an immediate reboot after invoking it (Supports from v1.0).
